In people with GHRH-producing, non-pituitary tumors, the pituitary still may be enlarged and may be mistaken for a tumor. Therefore, it is important that physicians carefully analyze all "pituitary tumors" removed from people with acromegaly to not overlook the possibility that a tumor elsewhere in the body is causing the disorder.

Hypophysectomy is the surgical removal of the hypophysis (pituitary gland). It is most commonly performed to treat tumors, especially craniopharyngioma tumors. [1] Sometimes it is used to treat Cushing's syndrome due to pituitary adenoma [2] or Simmond's disease [3] It is also applied in neurosciences (in experiments with lab animals) to understand the functioning of hypophysis.
After recovery, people who have had pituitary apoplexy require follow-up by an endocrinologist to monitor for long-term consequences. MRI scans are performed 3–6 months after the initial episode and subsequently on an annual basis. [1]
Some benign tumors are able to grow to a dangerous size because unlike other cells, “tumor cells have found a way to evade the normal life and death cycle of a cell — meaning they’ve learned ...
Surgery is a common treatment for pituitary tumors. The normal approach is trans-sphenoidal adenectomy, which usually can remove the tumor without affecting the brain or optic nerves. [70] Radiation is also used to treat pituitary adenomas. Examples include external beam or proton beam radiation therapy or stereotactic radiosurgery.
In one study of 261 patients with confirmed pituitary Cushing's disease, only 48% of pituitary lesions were identified using MRI prior to surgery. The average size of tumor, both those that were identified on MRI and those that were only discovered during surgery, was 6 mm. [ 14 ]
