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.
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.
Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
Pituicytoma is a rare brain tumor. It grows at the base of the brain from the pituitary gland. This tumor is thought to be derived from the parenchymal cells of the posterior lobe of the pituitary gland, called pituicytes. Some researchers [1] believe that they arise from the folliculostellate cells in the anterior lobe of the pituitary.
In a study of 1,034 symptomatic adults, Sheehan's syndrome was found to be the sixth-most frequent etiology of growth hormone deficiency, being responsible for 3.1% of cases (versus 53.9% due to a pituitary tumor). [8] Additionally, it was found that the majority of women who experienced Sheehan syndrome gave birth at home rather than in a ...

In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
Treatment of macroorchidism depends on pathogenesis. Surgical removal of the tumor is the most important and advised option for treating macroorchidism caused by non-functioning pituitary macroadenoma. [12] A non-functioning pituitary adenoma is a kind of benign tumor that does not secrete active hormones, and is from the pituitary gland. [13]
