Magnetic resonance imaging of cavernous sinus invasion by pituitary adenoma diagnostic criteria and surgical findings

Abstract: -This study used MRI to define preoperative imaging criteria for cavernous sinus invasion (CSI) by pituitary adenoma (PA). MR images of 103 patients with PA submitted to surgery (48 with CSI) were retrospectively reviewed. The following MR signs were studied and compared to intraoperative findings (the latter were considered the gold standard for CSI detection): presence of normal pituitary gland between the adenoma and CS, status of the CS venous compartments, CS size, CS lateral wall bulging, displacement of… Show more

“…However, a large proportion of adenomas are invasive and spread to sellar and/or parasellar tissues. 40 These invasions are not diagnostic of pituitary carcinoma; defined as metastatic tumors in the sellar region, they are exceedingly rare. Several studies have sought to identify features that could be used to predict the invasiveness of pituitary adenomas.…”
