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.
A CT or MRI of the pituitary may also show the ACTH-secreting tumor if present. However, in 40% of Cushing's disease patients MRI is unable to detect a tumor. [8] In one study of 261 patients with confirmed pituitary Cushing's disease, only 48% of pituitary lesions were identified using MRI prior to surgery.
However, if your Cushing syndrome is caused by a tumor—on your pituitary gland or adrenal gland—it’s usually removed by surgery. However, if the tumor is cancerous, chemotherapy may be ...
Cushing's syndrome is a collection of signs and symptoms due to prolonged exposure to glucocorticoids such as cortisol. [4] [9] [10] Signs and symptoms may include high blood pressure, abdominal obesity but with thin arms and legs, reddish stretch marks, a round red face due to facial plethora, [11] a fat lump between the shoulders, weak muscles, weak bones, acne, and fragile skin that heals ...
Inferior petrosal sinus sampling (or IPSS), is a diagnostic medical procedure used to determine whether excess adrenocorticotropic hormone (ACTH) is coming from the pituitary gland (usually a pituitary adenoma causing Cushing's disease) or from a source outside the pituitary (a rare tumor causing ectopic ACTH syndrome). The procedure is usually ...
If the tumor is found at the pituitary gland, neurosurgeons would perform the surgery either by craniotomy where the skull is opened and the whole pituitary gland is exposed for tumor cleaning, or by microsurgery where all surgical tools are placed into the brain through the nasal cavity.
Pituitary adenoma or craniopharyngioma: Tumors in the pituitary gland can suppress production of adrenocorticotropic hormone (ACTH). [2] High-dose irradiation (>30 Gy) to the hypothalamus or the pituitary gland can cause ACTH deficiency. [10] Surgery or radiation: Pituitary gland surgery and/or radiation can lead to destruction of ACTH ...
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 ...
