Description The pituitary gland...
Description
The pituitary gland is located below the brain, just behind the bridge of the nose. The pituitary gland controls the production of many hormones and a tumor in this area can cause alterations in these hormones. The optic nerve passes next to this gland in the brain, and tumors of the pituitary can affect vision by pressing on this nerve.

Workup:
A history and physical exam will be performed. Blood tests measure the hormones produced by the tumor. An MRI scan is done to view the tumor.
Tests:
Complete blood count (CBC), Comprehensive metabolic panel (CMP), CT Scan, Magnetic resonance imaging (MRI)
Other Specific Tests: Cortisol levels, follicle-stimulating hormone (FSH) levels, insulin growth factor-1 (IGF-1) levels, luteinizing hormone (LH) levels, serum prolactin levels, testosterone/estradiol levels, thyroid hormone levels

Treatment
Surgery to remove the tumor is often necessary. Most of the time, pituitary tumors can be removed through the nose and sinuses. Radiation therapy may be used to shrink the tumor. The following medications can reduce the symptoms from certain types of tumors: bromocriptine, cabergoline, octreotide, or pegvisomant.
