Pituitary Adenoma Treatment
The treatment of a pituitary adenoma is dependent on a number of factors including your age and general health, the size of the tumor, the extent that the tumor is invading surrounding tissue, and whether or not the tumor is producing hormones.
If the pituitary adenoma is producing hormones, it can sometimes be treated through medical management by a neuro-endocrinologist. Medication is often used in the treatment of prolactinomas, Cushing’s Disease, and acromegaly. Additionally, it is important to address pituitary failure before surgery.
If the pituitary adenoma requires surgical removal, this is typically done using a “transsphenoidal” approach. This surgical approach is done through the nose, and the sphenoid bone. Your surgeon will then continue deeper into the area that protects the pituitary gland. There is no outward scar following this procedure.
In some patients, the tumor may not be able to be removed surgically, and it may not respond to medical management. In this situation, you will most likely be treated via "stereotactic radiosurgery" (also sometimes referred to as a Gamma Knife). In fact, the treatment is done with precisely targeted radiation which disrupts the DNA of the tumor and interferes with its ability to survive. This will not remove the tumor but should stunt its growth. This radiation may cause some damage to the adjacent pituitary and thus must be delivered very carefully and precisely.
The primary risk is damage to your pituitary gland. Damage to the back portion of your pituitary gland can cause a condition known as diabetes insipidus. This condition limits your kidneys’ ability to concentrate urine, and causes frequent urination and excessive thirst. It can be treated with replacement of a hormone.
Other risks associated with pituitary surgery include infection, cerebrospinal fluid leakage, bleeding, hormone imbalance, and infection.
