The pituitary gland regulates the production and distribution of hormones in the body. Sometimes, tumors can develop on the pituitary gland, disrupting this function.

Symptoms of pituitary tumors

• Headaches
• Hormonal changes
• Hair loss
• Fatigue
• Nausea and vomiting
• Intolerance to cold
• Vision loss

Diagnosis of pituitary tumors

Your doctor will perform a complete medical evaluation, including a neurological exam to test your reflexes. He or she will also ask for a full medical and family history. Your doctor will probably order the following tests:

• Blood tests: to see the hormone levels in your blood
• CT scan or MRI scan: to see if the tumor can be identified on the scan

Your doctor may also refer you to a neuro-ophthalmologist. Because of the close location of the pituitary gland to the eyes, some tumors may affect vision. An endocrinologist may also recommend blood work to examine the hormone levels in your blood.

Treatment for pituitary tumors

Pituitary tumors are best managed by an interdisciplinary team of neurosurgeons, neurologists, otolaryngologists (ear, nose and throat physicians), and endocrinologists to determine the best course of action.

Your doctor may recommend surgery. Learn more about surgery for brain tumors at Georgetown by visiting the Acoustic Neuroma and Skull Base Tumor Center.
