Abstract

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