Intracranial Angiolipoma: A Case Report

Intracranial angiolipoma is extremely rare. We report the radiologic findings of angiolipoma in the rightmiddle cranial fossa, extending medially into the suprasellar and cavernous sinus region, in a 63-year-old woman.The lesion was a relatively well marginated extra-axial tumor that showed low density on precontrast CT and markedenhancement after contrast infusion. MR imaging showed heterogeneous low signal on T1W1 mixed with hyperintensefoci on T2W1, and marked enhancement after gadolinium infusion. On cerebral angiography, displacement of the rightinternal carotid artery by the tumor was seen. On an arteriogram of the right external carotid artery, the massshowed persistent capillary blush.
