Your pituitary gland is a small organ at the base of your brain. It creates hormones that are released into your bloodstream.

A pituitary adenoma is a slow-growing, noncancerous tumor that develops in the pituitary gland. Some tumors create hormones, which can cause problems like hyperthyroidism or gigantism. If the adenoma grows too big, it can put pressure on your brain or blood vessels, creating a life-threatening situation.

Many pituitary adenomas are too small to cause any symptoms at all. Some symptoms may include:

  • Achy joints or muscle weakness
  • Behavior changes
  • Changes to monthly periods
  • Fatigue
  • Headaches
  • Infertility
  • Nasal drainage
  • Nausea or vomiting
  • Sexual dysfunction
  • Unexplained weight gain or loss
  • Vision problems

Our expert physicians provide comprehensive treatment for symptomatic pituitary adenomas. They use the latest treatments to shrink or destroy tumors while keeping the brain safe and healthy.

  • Endoscopic Surgery

    Doctors can use small incisions and specialized tools to remove the pituitary adenoma through your nose.

  • Open Surgery

    If your tumor is too large or located in certain areas, your doctor may have to reach the tumor by making an opening in your skull.


  • Gamma Knife® Radiosurgery

    During Gamma Knife® radiosurgery, multiple weak beams of radiation are pointed at your tumor. Where all the beams meet, there is strong radiation. You may need only one radiosurgery treatment to destroy the adenoma.

  • Medicines

    In some cases, medicines can shrink the pituitary tumor. If the tumor shrinks enough, you may not need any other treatment.


  • Blood Test

    Blood tests can reveal if you have too much or too little of a hormone. Hormone imbalances may indicate a tumor.

  • Magnetic Resonance Imaging (MRI)

    An MRI is an imaging scan of your brain that uses no radiation but creates a highly detailed image of your brain.
