Case report: cushing disease caused by an ectopic intracavernous pituitary microadenoma: case report and review of the literature.


: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.

  • Use of high-pitch dual-source computed tomography of the abdomen and pelvis to markedly reduce scan time: clinical feasibility study.

    abstract:BACKGROUND:Increasing image pitch in computed tomographic (CT) imaging is a method through which scan time can be reduced, which can reduce motion artifacts. In this study, we assess the clinical feasibility of ultrahigh-pitch CT imaging made possible by dual-source CT. METHODS:Image pitch, total scan time, and image ...
