Adrenal Tumors

What are adrenal tumors?

Tumors of the adrenal glands are rare. However, when present, they can cause a multitude of disorders by excessively secreting certain adrenal-produced hormones. One type of tumor of the adrenal glands is called a pheochromocytoma.

What is a pheochromocytoma?

A pheochromocytoma is an adrenal gland tumor that secretes epinephrine and norepinephrine hormones. These hormones are responsible for regulating heart rate and blood pressure, among other functions. Pheochromocytomas occur most frequently in young to middle-aged adults between the ages of 30 and 60.

What are the symptoms of pheochromocytoma?

The most common symptom of pheochromocytoma is high blood pressure, which is sometimes extreme. Other symptoms are usually nonexistent, unless the person experiences pressure from the tumor, emotional stress, changes in posture, or is taking beta-blocker drugs for a heart disorder. Each individual may experience symptoms differently. Other symptoms may include:

rapid pulse
palpitations
headache
nausea
vomiting
clammy skin

The symptoms of pheochromocytoma may resemble other conditions or medical problems. Always consult your physician for a diagnosis.

How is pheochromocytoma diagnosed?

In addition to a complete medical history and medical examination, diagnostic procedures for pheochromocytoma may include:

blood and urine tests to measure hormone levels
computed tomography (CT or CAT scan) - a non-invasive procedure that takes cross-sectional images of the brain or other internal organs; to detect any abnormalities that may not show up on an ordinary x-ray
radioisotope scan - uses radioactive substances introduced into the body to create an image of the functioning adrenal gland

Treatment for pheochromocytoma:

Treatment for pheochromocytoma usually includes removing the tumor. Before removing the tumor, however, your physician may prescribe drugs to control high blood pressure.
