Pituitary adenomas cause significant morbidity caused by compression of regional structures or the inappropriate expression of pituitary hormones. However, little is known about the molecular changes that contribute to the development of these tumors. To investigate these changes, we recently used cDNA microarray analysis to identify several genes with altered expression patterns in pituitary a...
UNLABELLED The objective of this study was to evaluate the in vivo assay of folate receptors in nonfunctional pituitary adenomas using preoperative (99m)Tc-folate SPECT/CT and Western blot analysis (WBA) of surgical specimens as the standard. METHODS Fifty-six patients (29 men, 27 women; age range, 29-82 y) with clinically nonfunctional pituitary adenomas on MRI underwent preoperative imaging...
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...
Pituitary apoplexy is a medical condition that needs urgent diagnosis and treatment. It may occur spontaneously or may be precipitated by a variety of reasons including dynamic endocrine tests. Although pituitary apoplexy is usually seen in nonfunctional pituitary adenoma, it can also be seen in ACTH secreting macroadenomas. ACTH secreting adenomas present usually as microadenomas and in these ...
OBJECT Pituitary adenomas are fairly common intracranial neoplasms, and nonfunctioning ones constitute a large subgroup of these adenomas. Complete resection is often difficult and may pose undue risk to neurological and endocrine function. Stereotactic radiosurgery has come to play an important role in the management of patients with nonfunctioning pituitary adenomas. This study examines the o...
