Pituitary adenomas are tumors that occur in the pituitary gland. Most pituitary tumors are benign, approximately 35% are invasive and just 0.1% to 0.2% are carcinomas. [1] Pituitary adenomas represent from 10% to 25% of all intracranial neoplasms, with an estimated prevalence rate in the general population of approximately 17%. [1] [2]
Last Mexican governor of California; suffered from Acromegaly between at least 1847 to 1858, followed by selective pituitary tumor apoplexy with reversal of all tumor manifestations and survival to 1894 Growth hormone–secreting pituitary adenoma with apoplexy 1847–1894 [215] Cecile Richards: 1957-2025
Pituitary adenomas are responsible for 80% of endogenous Cushing's syndrome, [3] when excluding Cushing's syndrome from exogenously administered corticosteroids. The equine version of this disease is Pituitary pars intermedia dysfunction. This should not be confused with ectopic Cushing syndrome or exogenous steroid use. [4]
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 ...
Adenomas are benign tumors of gland-forming cells, and are usually specified further by their cell or organ of origin, as in hepatic adenoma (a benign tumor of hepatocytes, or liver cells). Teratomas contain many cell types such as skin, nerve, brain and thyroid, among others, because they are derived from germ cells. [ 36 ]
Scientists have identified a biomarker for Alzheimer's that may help doctors spot the early signs of protein buildup in the brain before it causes significant damage.
The pituitary gland consists of two parts, the anterior (front) and posterior (back) pituitary. Both parts release hormones that control numerous other organs. In pituitary apoplexy, the main initial problem is a lack of secretion of adrenocorticotropic hormone (ACTH, corticotropin), which stimulates the secretion of cortisol by the adrenal ...
