Pituitary Tumors and Disorders

Having a pituitary tumor or disease can be frightening. You may feel sick from hormone imbalances and have severe headaches or vision loss.

The experts at the OHSU Northwest Pituitary Center will work with you from the time you are diagnosed with a pituitary disorder through treatment and management. Our team brings together decades of experience and skill to provide you with the best care available.

The OHSU Northwest Pituitary Center is a leader in pituitary care. We perform more pituitary diagnoses, second opinions and procedures of every type than any other medical center in the region. Each year, we treat more than 500 new patients from across the country. We also give you access to clinical trials, studies of new medications or treatments that may help your condition. 

Medical treatment

We have expertise with medications that can treat pituitary conditions. Your doctor can determine whether your condition will be permanently controlled after taking medication. If you need to take hormones, your doctors will help you choose the best way to take them. Pituitary conditions can be treated with medication, but you may also need surgery.
Pituitary diseases can develop when the pituitary gland makes too much of a certain hormone. For example:

  • Making too much growth hormone (GH) can result in acromegaly.
  • Making too much adrenocorticotropic hormone (ACTH) results in Cushing’s syndrome.

There are medications that can help treat pituitary disorders if you cannot have surgery or prefer to take medication instead. These drugs can often control your pituitary condition permanently. Often, you may stop taking them after some time.

Surgical treatment

You may need surgery to remove a pituitary tumor.

Here at OHSU, surgeons use an intraoperative MR imaging machine to obtain real-time imaging to help perform piuitary tumor surgery more accurately with minimal risk.

Microscopic surgery

While you are under anesthesia, we will use the imaging equipment to locate the tumor. Your doctor will make a small incision inside the nostril and remove the tumor using a microscope and tiny instruments.

Endoscopic surgery

Your doctor may also do surgery with an instrument called an endoscope. This uses a tiny camera to help locate the tumor. It is easier to see the tumor than with a microscope. We also can use imaging equipment in this surgery to make it even more precise.
