Pituitary Tumors

Pituitary adenomas are tumors in the pituitary gland, located in the center of the head behind the eyes. The pituitary gland is less than a half inch in diameter and controls many of the body's hormones — chemicals that regulate essential body processes.

UCSF Medical Center is a major center for the diagnosis and treatment of pituitary disorders. The California Center for Pituitary Disorders at UCSF provides the most advanced diagnostic services and treatments including neurosurgery, radiation therapy and medication. The center is staffed by doctors who are known internationally for their expertise in treating pituitary tumors.

There are several types of pituitary tumors. Some tumors may cause Cushing's disease, in which too many hormones called glucocorticoids are released into the bloodstream. This causes fat to build up in the face, back and chest while the arms and legs become very thin. Other symptoms include too much sugar in the blood, weak muscles and bones, a flushed face and high blood pressure.

Other pituitary tumors can cause a condition called acromegaly, where the hands, feet and face are larger than normal. In very young people, the entire body may grow much larger than normal.

Almost all pituitary tumors are benign, rather than malignant or cancerous, and are relatively slow growing. They rarely spread to other areas of the body.
