Female, 58 years old, with history of cavernoma status post resection in March 2016, postoperative surveillance examination. Postoperative findings are seen compatible with cavernoma resection from the right precentral gyrus. A small resection cavity is demonstrated at the site of the prior lesion. The cavity is mildly hemosiderin stained. Chronic hemosiderin staining of the adjacent parenchyma remains similar to that seen on the preoperative evaluation. Minimal intrinsic T1 hyperintensity is seen within the resection cavity with a small degree of superimposed enhancement, reduced when compared to the preoperative examination.The dura underlying the right parietal bone craniotomy is mildly thickened and enhancing, an expected postoperative finding. No other pathologic intracranial enhancement is seen. Scattered foci of white matter T2 hyperintensity are redemonstrated without significant interval change. No new edema or mass effect is detected. The ventricles are stable and normal in size. Opacification of the right maxillary sinus is a stable finding.
Expected postoperative findings are seen status post resection of a cavernous malformation from the right precentral gyrus.
