Benefit Summary
Learn more about the symptoms, causes and treatment of growths that develop in the pituitary gland.
Overview
, Overview, ,
Pituitary tumors are unusual growths that develop in the pituitary gland. This gland is an organ about the size of a pea. It’s located behind the nose at the base of the brain. Some of these tumors cause the pituitary gland to make too much of certain hormones that control important body functions. Others can cause the pituitary gland to make too little of those hormones.
Most pituitary tumors are benign. That means they are not cancer. Another name for these noncancerous tumors is pituitary adenomas. Most adenomas stay in the pituitary gland or in the tissue around it, and they grow slowly. They typically don’t spread to other parts of the body.
Pituitary tumors can be treated in several ways. The tumor may be removed with surgery. Or its growth may be controlled with medications or radiation therapy. Sometimes, hormone levels are managed with medicine. Your health care provider may suggest a combination of these treatments. In some cases, observation — also called a ”wait-and-see” approach — may be the right choice.
Types
Types of pituitary adenomas include:
- Functioning. These adenomas make hormones. They cause different symptoms depending on the kind of hormones they make. Functioning pituitary adenomas fall into several categories, including those that make:
- Adrenocorticotropic hormone. This hormone also is known as ACTH. These tumors are sometimes called corticotroph adenomas.
- Growth hormone. These tumors are called somatotroph adenomas.
- Luteinizing hormone and follicle-stimulating hormone. These hormones also are known as gonadotropins. Pituitary tumors that make these hormones are called gonadotroph adenomas.
- Prolactin. These tumors are called prolactinomas or lactotroph adenomas.
- Thyroid-stimulating hormone. These tumors are called thyrotroph adenomas.
- Nonfunctioning. These adenomas don’t make hormones. The symptoms they cause are related to the pressure their growth puts on the pituitary gland, nearby nerves and the brain.
- Macroadenomas. These are larger adenomas. They measure about 1 centimeter or more. That’s slightly less than a half-inch. They can be functioning or nonfunctioning.
- Microadenomas. These adenomas are smaller. They measure less than 1 centimeter. That’s slightly less than a half-inch. They can be functioning or nonfunctioning.
Pituitary tumors are different from pituitary cysts. A cyst is a sac that may be filled with air, fluid or other material. A tumor is an unusual mass of cells that may grow over time. Cysts may form on or near the pituitary gland, but they are not tumors or adenomas.
Pituitary tumors are tumors that form in the pituitary gland near the brain. These tumors can cause changes in hormone levels. This illustration shows a smaller tumor, called a microadenoma.

Pituitary tumor Symptoms
Not all pituitary tumors cause symptoms. Sometimes these tumors are found during an imaging test, such as an MRI or a CT scan, that is done for another reason. If they don’t cause symptoms, pituitary tumors usually don’t need treatment.
Pituitary tumor symptoms may be caused by a tumor putting pressure on the brain or on other parts of the body nearby. Symptoms also can be caused by a hormone imbalance. Hormone levels can rise when a pituitary tumor makes too much of one or more hormones. Or a large tumor that disrupts the way the pituitary gland works may cause hormone levels to fall.
Symptoms from tumor pressure
Macroadenomas can put pressure on the pituitary gland, on nerves, on the brain and on other parts of the body nearby. That can cause symptoms such as:
- Headache.
- Eye problems due to pressure on the optic nerve, especially loss of side vision, also called peripheral vision, and double vision.
- Pain in the face, sometimes including sinus pain or ear pain.
- Drooping eyelid.
- Seizures.
- Nausea and vomiting.
Symptoms from hormone changes
Low amounts of hormones
Macroadenomas can limit the pituitary gland’s ability to make hormones. When that happens, symptoms may include:
- Tiredness or weakness.
- Lack of energy.
- Sexual problems, such as problems with erections and less interest in sex.
- Changes in menstrual cycles.
- Nausea.
- Feeling cold.
- Losing or gaining weight without trying.
High amounts of hormones
Functioning pituitary adenomas typically make a large amount of one hormone. That exposes the body to high levels of that hormone. Rarely, a pituitary adenoma may make more than one hormone. The following types of functioning pituitary adenomas cause different symptoms depending on the hormones they make.
Pituitary tumors that make adrenocorticotropic hormone
Pituitary tumors that make adrenocorticotropic hormone are called corticotroph adenomas. Adrenocorticotropic hormone, also called ACTH, causes the adrenal glands to make the hormone cortisol. ACTH tumors trigger the adrenal glands to make too much cortisol. This causes a condition called Cushing disease. Cushing disease is one cause of Cushing syndrome.
Cushing disease symptoms include:
- Weight gain and fatty tissue deposits around the midsection and upper back.
- Rounded face.
- Stretch marks.
- Thin skin that bruises easily.
- Thinning of the arms and legs with muscle weakness.
- Thicker or more visible body hair.
- Slow healing of cuts, insect bites and infections.
- Areas of darkened skin.
- Acne.
- Changes in menstrual cycles.
- Sexual problems, including problems with erections and less interest in sex.
Pituitary tumors that make growth hormone
Pituitary tumors that make growth hormone also are called growth hormone-secreting tumors or somatotroph adenomas. Too much growth hormone leads to a condition known as acromegaly. Acromegaly can cause:
- Changes in facial features, including larger lips, nose and tongue; longer lower jaw; and wide spaces between teeth.
- Growth of hands and feet.
- Thicker skin.
- More sweating and body odor.
- Joint pain.
- A deeper voice.
Children and teens who have too much growth hormone might also grow faster or taller than usual. This condition is called gigantism.
Pituitary tumors that make luteinizing hormone and follicle-stimulating hormone
Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are also known as gonadotropins. Pituitary tumors that make these hormones are called gonadotroph adenomas.
It’s uncommon for these adenomas to make too many hormones that then trigger symptoms. Instead, symptoms from these adenomas usually are due to tumor pressure. If symptoms do happen because of too much LH and FSH, they affect women and men differently.
Symptoms in women may include:
- Change in menstrual cycles.
- Fertility problems.
- Enlargement of and pain in the ovaries caused by a condition called ovarian hyperstimulation syndrome.
Symptoms in men may include:
- Enlarged testicles.
- Higher levels of testosterone.
Pituitary tumors that make prolactin
These adenomas are called prolactinomas. Too much of the hormone prolactin can lead to a decrease in the body’s levels of sex hormones — estrogen and testosterone. Too much prolactin affects men and women differently.
In women, too much prolactin might cause:
- Irregular menstrual cycles.
- Lack of menstrual cycles.
- Milky discharge from the breasts.
- Breast tenderness.
- Problems with fertility.
- Less interest in sex.
In men, too much prolactin can cause a condition called male hypogonadism. Symptoms might include:
- Problems with erections.
- Less interest in sex.
- Breast growth.
- Problems with fertility.
- Less body and facial hair.
Pituitary tumors that make thyroid-stimulating hormone
Pituitary tumors that make thyroid-stimulating hormone are called thyrotroph adenomas. They also may be referred to as thyroid-stimulating hormone-secreting tumors. They cause the thyroid gland to make too much of the hormone thyroxine, also called T-4. That leads to a condition called hyperthyroidism, also known as overactive thyroid disease. Hyperthyroidism can speed up the body’s metabolism causing many symptoms. Some of the most common include:
- Weight loss.
- Rapid or irregular heartbeat.
- Nervousness, anxiety or irritability.
- Frequent bowel movements.
- Sweating.
- Tremor.
- Sleep problems.
When to see a doctor
If you develop symptoms that might be associated with a pituitary tumor, see your health care provider. Treatment for pituitary tumors often can bring hormones back to a healthy level and ease symptoms.
Although rare, some pituitary tumors are hereditary. That means they run in families. In particular, the hereditary disorder multiple endocrine neoplasia, type 1 (MEN 1) can cause pituitary tumors. If MEN 1 runs in your family, talk to your health care provider about tests that may help find a pituitary tumor early.
Without treatment, Cushing syndrome can cause facial roundness, weight gain around the middle body and upper back, thinning of the arms and legs, easy bruising, and stretch marks.

Symptoms of acromegaly include an enlarged face and hands. Changes to the face may cause the brow bone and lower jawbone to protrude, and the nose and lips to get larger.

The pituitary gland is a small organ about the size of a pea. It’s located behind the nose at the base of the brain. Despite its small size, the pituitary gland has an effect on nearly every part of the body. The hormones it makes control important body functions, such as growth, blood pressure and reproduction.
The cause of uncontrolled cell growth in the pituitary gland, which creates a tumor, remains unknown. In rare cases, pituitary tumors can be caused by genes you’ve inherited. But most have no clear hereditary cause. Still, scientists think that changes in genes may play an important role in how pituitary tumors develop.
The pituitary gland and the hypothalamus are in the brain. They control hormone production.
Pituitary gland and hypothalamus Risk factors
Most people who get pituitary tumors don’t have any factors that put them at higher risk of developing these tumors. Environment and lifestyle choices don’t seem to have an effect on a person’s risk of pituitary tumors.
Although genetics seems to play a role, most people who have pituitary tumors don’t have a family history of them.
The only known risk factors are several rare hereditary conditions that raise the risk of many health problems, including pituitary tumors. These conditions include:
- Multiple endocrine neoplasia, type 1, also called MEN 1.
- Multiple endocrine neoplasia, type 4, also called MEN 4.
- Carney complex.
- McCune-Albright syndrome.
Complications
Pituitary tumors usually don’t spread to other parts of the body. They can affect a person’s health, though. Pituitary tumors may cause:
- Problems with eyesight, including vision loss.
- High blood pressure.
- High blood sugar.
- Bone loss.
- Heart problems.
- Problems with thinking and memory.
Seizures
If a pituitary tumor presses on part of the brain called the medial temporal lobe, it may lead to a seizure. This type of seizure is known as a focal seizure with impaired awareness. These seizures involve a change in or loss of consciousness or awareness. If you have one of these seizures, you may seem to be awake. But you stare into space and don’t respond as you typically would to the environment around you. You may not remember the seizure after it happens.
Permanent low hormone levels
Having a pituitary tumor or having one removed with surgery may permanently change your body’s hormone supply. As a result, you may need hormone replacement therapy for the rest of your life.
Pituitary apoplexy
A rare but potentially serious complication of a pituitary tumor is pituitary apoplexy. This happens when there is sudden bleeding into the tumor. Symptoms include:
- A severe headache, likely worse than you’ve ever had before.
- Problems with your eyesight, including double vision or loss of vision in one or both eyes.
- Nausea and vomiting.
- Confusion or other reduced mental function.
Pituitary apoplexy requires emergency treatment. The treatment usually includes taking corticosteroid medicine to ease swelling around the tumor. You also may need surgery to remove the tumor.
Diagnosis
Pituitary tumors often aren’t noticed or aren’t detected. In many cases, that’s because the symptoms caused by pituitary tumors that make hormones, called functioning adenomas, and large tumors, called macroadenomas, are similar to those of other medical conditions. It’s also because they grow very slowly over time. Small pituitary tumors that don’t make hormones, called nonfunctioning microadenomas, often don’t cause symptoms. If they are detected, it’s typically because of an imaging exam, such as an MRI or a CT scan, that’s done for another reason.
To detect and diagnose a pituitary tumor, your health care provider will likely talk with you about your personal and family medical history and do a physical exam. Testing to detect a pituitary tumor also may include:
-
Blood tests. Blood tests can show whether your body has too much or too little of certain hormones. For some hormones, blood test results that show too much of the hormone may be all that’s needed for your health care provider to diagnose a pituitary adenoma.
For other hormones, such as cortisol, a blood test result that shows too much of the hormone may need to be followed by other tests. Those tests can show if the earlier result was caused by a pituitary adenoma or by another health concern.
Results that show hormone levels are too low need to be followed with other tests, usually imaging exams, to see if a pituitary adenoma may be the cause of those test results.
- Urine tests. A urine test may be used to help diagnose a pituitary adenoma that’s making too much of the hormone ACTH. Too much ACTH leads to too much cortisol in the body and causes Cushing disease.
- MRI scan. A magnetic resonance imaging scan, also called an MRI scan, is a test that uses a magnetic field and computer-generated radio waves to create detailed images of the body’s organs and tissues. An MRI of the brain can help detect a pituitary tumor and show its location and size.
- CT scan. A computed tomography scan, also called a CT scan, is a type of imaging test that combines a series of X-rays to create cross-sectional images. MRI scans are used more often than CT scans to detect and diagnose pituitary tumors. But a CT scan may be helpful in planning surgery if your health care provider tells you that a pituitary tumor must be removed.
- Vision testing. A pituitary tumor can affect eyesight, especially side vision, also called peripheral vision. Testing your eyes to check how well you can see may help your health care provider decide if other tests may be needed to detect a pituitary tumor.
Your health care provider may refer you to a specialist in hormone disorders, called an endocrinologist, for more testing.
Treatment
Many pituitary adenomas don’t need treatment. They are not cancer, so if they don’t cause symptoms, simply watching them over time may be a good approach. If treatment is needed, the specific treatment depends on the tumor type, size, location and growth over time. If a tumor is causing too much or too little of certain hormones in the body, that also affects the treatment. Your age and overall health play a role in treatment planning too.
The goal of treatment is to:
- Return hormone levels to a healthy range.
- Avoid more damage to the pituitary gland and restore its regular function.
- Reverse symptoms caused by tumor pressure or prevent them from getting worse.
If a pituitary adenoma needs treatment, it may include surgery to remove the tumor. Medication or radiation therapy also might be used to treat a pituitary adenoma. Treatment involves a team of medical experts. The team may include a:
- Brain surgeon, also called a neurosurgeon.
- Nose and sinus surgeon, also called an ENT surgeon.
- Hormone disorder specialist, also called an endocrinologist.
- Radiation therapy specialist, also called a radiation oncologist.
Surgery
Surgery to treat a pituitary tumor involves removing the tumor. This is sometimes called a tumor resection. A surgeon may suggest surgery if a pituitary adenoma:
- Presses on the optic nerves and limits eyesight.
- Causes other symptoms, such as headache or facial pain.
- Lowers hormone levels in the body due to pressure on the pituitary gland.
- Causes the body to make too much of some hormones.
Results after surgery typically depend on the adenoma type, its size and location, and whether the tumor has grown into tissues around it.
Surgeries to remove a pituitary tumor include endoscopic transnasal transsphenoidal surgery and craniotomy.
Endoscopic transnasal transsphenoidal surgery
This surgery also is called adenomectomy. It’s the most common surgery used to remove a pituitary adenoma.
During the surgery, a surgeon — typically a neurosurgeon partnering with a nose and sinus surgeon — removes the adenoma through the nose and sinuses. The surgery doesn’t require an external cut, also called an incision. It does not affect other parts of the brain. The surgery doesn’t cause a scar that you can see.
Large macroadenomas may be hard to remove with this surgery. That’s particularly true if a macroadenoma has spread to nearby nerves, blood vessels or other parts of the brain.
Transcranial surgery
This surgery also is called a craniotomy. It’s used less often than endoscopic transnasal transsphenoidal surgery for pituitary tumors. This surgery makes it easier to reach and remove large macroadenomas or pituitary tumors that have spread to nearby nerves or brain tissue. It also makes it easier for the surgeon to see the extent of the tumor, as well as the parts of the brain around it. During transcranial surgery, the surgeon removes the tumor through the upper part of the skull through a cut in the scalp.
Endoscopic transnasal transsphenoidal surgery and transcranial surgery are generally safe procedures. Complications are uncommon. But as with any surgery, there are risks. Complications after pituitary tumor surgery can include:
- Bleeding.
- Infection.
- Reaction to the medicine that puts you in a sleep-like state during surgery This sleep-like state is called anesthesia.
- Temporary headache and nasal congestion.
- Brain injury.
- Double vision or loss of vision.
- Damage to the pituitary gland.
Diabetes insipidus
Surgery to remove a pituitary tumor might damage the pituitary gland. That can limit its ability to make hormones, leading to other medical problems including diabetes insipidus. This condition happens when the pituitary gland cannot make enough of the hormone vasopressin. That hormone is made in the back of the gland, an area called the posterior pituitary. Diabetes insipidus causes the body’s fluids to go out of balance, which then causes the body to make large amounts of urine. That can cause extreme thirst and raise the risk of dehydration. Diabetes insipidus after surgery to remove a pituitary tumor usually is short term. It typically goes away without treatment within a few days. If diabetes insipidus lasts longer than that, treatment with a manufactured form of vasopressin may be used. The condition often goes away after several weeks or months.
If your health care provider suggests surgery to treat a pituitary tumor, ask about which surgery is right for you. Talk about the possible complications, risks and side effects. Ask what you can expect during recovery.
Radiation therapy
Radiation therapy uses high-energy sources of radiation to treat pituitary tumors. Radiation therapy can be used after surgery. Or it can be used alone if surgery isn’t an option.
Radiation therapy can be helpful if a pituitary tumor:
- Isn’t completely removed with surgery.
- Comes back after surgery.
- Causes symptoms that medications don’t relieve.
The goal of radiation therapy for pituitary adenomas is to control adenoma growth or to stop the adenoma from making hormones.
Methods of radiation therapy that can be used to treat pituitary tumors include:
- Stereotactic radiosurgery. Often delivered as a single high dose, this type of radiation therapy precisely focuses radiation beams on the tumor. Although the word “surgery” is in its name, no cut into the skin is needed. It delivers radiation beams the size and shape of the tumor into the tumor with the aid of brain-imaging techniques. This requires attaching a head frame to the skull. The frame is removed right after treatment. Little radiation comes in contact with healthy tissue near the tumor. That lowers the risk of damage to the healthy tissue.
- External beam radiation. This method also is called fractionated radiation therapy. It delivers radiation in small amounts over time. A series of treatments usually is done five times a week for 4 to 6 weeks.
- Intensity modulated radiation therapy. This type of radiation therapy, also called IMRT, uses a computer that allows the beams to be shaped to surround the tumor from many angles. The strength of the beams can be limited. That lowers the risk of side effects on healthy tissue.
- Proton beam therapy. Another radiation option, proton beam therapy uses positively charged ions, called protons, to target tumors. Proton beams stop after releasing their energy within the tumor. This means the beams can be controlled to target a pituitary adenoma with less risk of side effects in healthy tissue. This type of radiation therapy requires special equipment. It isn’t widely available.
Potential side effects and complications of radiation therapy for pituitary adenomas can include:
- Damage to the pituitary gland that limits its ability to make hormones.
- Damage to healthy tissue near the pituitary gland.
- Vision changes due to damage to the optic nerves.
- Damage to other nerves close to the pituitary gland.
- Slightly increased risk of developing a brain tumor.
A radiation oncologist evaluates your condition and talks with you about the benefits and risks of radiation therapy for your situation. It usually takes months to years to see the maximum benefit of radiation therapy for pituitary adenomas. Side effects and complications from radiation therapy usually don’t show up right away either. It is important to have regular long-term follow-up care to detect any hormone problems that may happen due to radiation therapy.
Medications
Treatment with medications can be useful for the management of pituitary adenomas. They can help lower the amount of hormones the body makes due to a tumor. Some medications also can shrink certain types of pituitary tumors.
Pituitary tumors that make prolactin
The following medications are used to lower the amount of prolactin a pituitary adenoma makes. They also can often shrink the tumor.
- Cabergoline.
- Bromocriptine (Parlodel, Cycloset).
Possible side effects include:
- Dizziness.
- Mood disorders, including depression.
- Headache.
- Weakness.
Some people develop compulsive behaviors, such as problems with gambling, while taking these medications. Those behaviors also are called impulse control disorders.
Pituitary tumors that make adrenocorticotropic hormone
Tumors that make adrenocorticotropic hormone, also called ACTH, cause the body to make too much cortisol. That condition is known as Cushing disease. Medications that can lower the amount of cortisol the body makes include:
- Ketoconazole.
- Metyrapone (Metopirone).
- Osilodrostat (Isturisa).
Possible side effects of these medications include a heart problem that can lead to a serious heartbeat irregularity.
Another medication called mifepristone (Korlym, Mifeprex) can be used for people with Cushing disease who have type 2 diabetes or glucose intolerance. Mifepristone doesn’t lower the amount of cortisol the body makes. Instead, it blocks the effects of cortisol on the body’s tissues.
Side effects of mifepristone include:
- Tiredness.
- Weakness.
- Nausea.
- Heavy vaginal bleeding.
The medication pasireotide (Signifor) works by lowering the amount of ACTH a pituitary adenoma makes. It’s taken as a shot twice a day. Providers typically suggest pasireotide when surgery to remove an adenoma doesn’t work. It also may be used when an adenoma can’t be removed with surgery.
Side effects of pasireotide include:
- Diarrhea.
- Nausea.
- High blood sugar.
- Headache.
- Stomach pain.
- Tiredness.
Pituitary tumors that make growth hormone
Two kinds of medication can treat pituitary tumors that make growth hormone. Providers often prescribe these medications when surgery to remove a pituitary adenoma hasn’t worked to return the amount of growth hormone in the body to a healthy level.
-
Somatostatin analogs. This type of medication lowers the amount of growth hormone that the body makes. It also may partially shrink a pituitary adenoma. Somatostatin analogs include:
- Octreotide (Sandostatin).
- Lanreotide (Somatuline Depot).
These medications are given as a shot, usually every four weeks. A form of octreotide that can be taken in a pill, called Mycapssa, also is available. It works like the forms that are given as a shot and has similar side effects.
Side effects of somatostatin analogs include:
- Nausea and vomiting.
- Diarrhea.
- Stomach pain.
- Dizziness.
- Headache.
- Pain at the site of the shot.
- Gallstones.
- Worsening diabetes.
Many of these side effects improve over time.
- Pegvisomant (Somavert). This medication blocks the effect of too much growth hormone on the body. It’s taken as a shot every day. This medication may cause the side effect of liver damage in some people.
Pituitary hormone replacement
The pituitary gland controls growth, thyroid function, adrenal function, reproductive function and the balance of water in the body. One or all of those can be harmed by a pituitary adenoma or by its treatment with surgery or radiation. This is because of the hormone changes they can cause. If your hormones fall to unhealthy levels, you may need to take hormone replacement therapy. This can restore hormones to a healthy level.
Watchful waiting
In watchful waiting — also known as observation, expectant therapy or deferred therapy — you might need regular follow-up tests to see if a tumor grows or if hormone levels change. Watchful waiting may be a choice for you if an adenoma isn’t causing any symptoms or triggering other health problems. Talk to your health care provider about the benefits and risks of watchful waiting versus treatment in your situation.
In transnasal transsphenoidal endoscopic surgery, a surgical instrument is placed through the nostril and alongside the nasal septum to access a pituitary tumor.
Endoscopic transnasal transsphenoidal surgery Coping and support
It’s natural for you to have questions throughout the diagnosis and treatment of a pituitary tumor. The process can be overwhelming and sometimes scary. That’s why it’s important to learn as much as you can about your condition. The more you know and understand about your care, the better.
You might find it helpful to share your feelings with other people who are in a situation like yours. Check to see if support groups for people with pituitary tumors are available in your area. Hospitals often sponsor these groups. Your health care provider may be able to help you find the emotional support you need.
Preparing for an appointment
You’re likely to start by seeing your primary care provider. If your provider thinks you might have a pituitary tumor, the next step may be appointments with specialists. Those specialists may include a nose and sinus surgeon, a brain surgeon — also called a neurosurgeon — or an endocrinologist — a doctor who specializes in hormone disorders.
Here’s some information to help you prepare for your appointment.
What you can do
When you make the appointment, ask if there’s anything you need to do in advance, such as not eating before having a specific test. Make a list of:
- Your symptoms, including any that may seem unrelated to the reason for your appointment.
- Key personal information, including major stresses or recent life changes and family medical history.
- Medicines, vitamins or supplements you take, including doses.
- Questions to ask your health care provider.
Take a family member or friend along, if possible, to help you remember the information you receive.
For a pituitary tumor, questions to ask your health care provider include:
- What is likely causing my symptoms or condition?
- What are other possible causes?
- What specialists should I see?
- What tests do I need?
- What is the best course of action?
- What are alternatives to the approach you’re suggesting?
- I have other health conditions. How can I manage them together?
- Are there restrictions I need to follow?
- Are there brochures or other printed materials I can have? What websites do you recommend?
Don’t hesitate to ask other questions.
What to expect from your doctor
Your health care provider is likely to ask you a number of questions, including:
- When did your symptoms begin?
- Have they been continuous or occasional?
- How severe are your symptoms?
- What, if anything, seems to improve your symptoms?
- What, if anything, appears to worsen your symptoms?
- Have you had imaging tests done of your head for any reason in the past?
