Adenomas exceeding 10 mm (0.39 in) in size are defined as macroadenomas, while those smaller than 10 mm (0.39 in) are referred to as microadenomas. Most pituitary adenomas are microadenomas and have an estimated prevalence of 16.7% (14.4% in autopsy studies and 22.5% in radiologic studies).
Pituitary apoplexy is regarded by some as distinct from Sheehan's syndrome, where the pituitary undergoes infarction as a result of prolonged very low blood pressure, particularly when caused by bleeding after childbirth. This condition usually occurs in the absence of a tumor. [4] Others regard Sheehan's syndrome as a form of pituitary apoplexy.
Hyperpituitarism is a condition due to the primary hypersecretion of pituitary hormones; [3] [medical citation needed] it typically results from a pituitary adenoma.In children with hyperpituitarism, disruption of growth regulation is rare, either because of hormone hypersecretion or because of manifestations caused by local compression of the adenoma.
[3] [4] Chronic pain is considered a syndrome because of the associated symptoms that develop in those experiencing this disorder. [5] Chronic pain affects approximately 20% of people worldwide and accounts for 15–20% of visits to a physician. [3] Pain can be categorized according to its location, cause, or the anatomical system which it affects.
Autoimmune hypophysitis (or lymphocytic hypophysitis), inflammation of the pituitary gland due to autoimmunity. Nelson's syndrome, may occur after surgical removal of both adrenal glands, an out-dated method of treating Cushing's disease. Pituitary tumour, a tumor of the pituitary gland. Pituitary adenoma, a noncancerous tumor of the pituitary ...
While a plain X-ray of the bones surrounding the pituitary may reveal the presence of a large macroadenoma, small microadenomas will not be apparent. Magnetic resonance imaging ( MRI ) is the most sensitive test for detecting pituitary tumors and determining their size. [ 2 ]
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 ...
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]
