title: Case report: cushing disease caused by an ectopic intracavernous pituitary microadenoma: case report and review of the literature.
abstract: Despite increasing performance of pituitary imaging, adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas are often difficult to identify because of their small size and variable location. We present a case of ACTH-dependent Cushing syndrome in which the demonstration of the cavernous sinus localization of a microadenoma was made by magnetic resonance imaging (MRI). Ectopic pituitary microadenomas have been described only in a few reports, and the current case-report is the first to our knowledge to illustrate clearly the intracavernous localization of the microadenoma.
