Nonfunctional pituitary macroadenoma manifested as muscular symptoms.

Spontaneous regression of one nonfunctioning pituitary macroadenoma associated with abnormal liver enzyme tests

Background: Nowadays, drug and observation are advised to patients with lymphocytic hypophysitis and in some cases with nonfunctioning pituitary macoadenoma, instead of surgery. Case presentation: In this article, we report a woman with nonfunctional pituitary macroadenoma and panhypopitutarism and negative criteria for lymphocytic hypophysitis associated with increased liver enzymes. After thr...

A pediatric case of pituitary macroadenoma presenting with pituitary apoplexy and cranial nerve involvement: case report.

Pituitary adenomas usually arise from the anterior lobe of the pituitary gland and are manifested with hormonal disorders or mass effect. Mass effect usually occurs in nonfunctional tumors. Pituitary adenomas may be manifested with visual field defects or rarely in the form of total oculomotor palsy. Visual field defect is most frequently in the form of bitemporal hemianopsia and superior tempo...

Thyrotropin secreting pituitary adenoma accompanying a silent somatotropinoma.

Thyroid stimulating hormone (TSH) secreting pituitary adenomas are rare tumors manifested as hyperthyroidism with goiter in the presence of elevated TSH. We present a case with pituitary adenoma secreting both TSH and growth hormone (GH) with the prominent clinical findings of hyperthyroidism but without clinical findings of acromegaly. Pituitary magnetic resonance imaging revealed a macroadeno...

A FSH-Secreting Pituitary Macroadenoma Causing A Testosterone Deficiency Syndrome

170 - Pituitary Apoplexy

The posterior lobe is an extension of the hypothalamus and secretes two hormones: antidiuretic hormone (or arginine vasopressin) and oxytocin. The pituitary stalk and the portal vessel pass through a small diaphragm that separates the sella turcica from the middle fossa. This anatomic arrangement places the pituitary at risk for infarction or hemorrhage when a mass increases pressure in the sel...
