Intracranial angiolipoma: report of two cases.

Intracranial tumours composed of adipose tissue and abnormal blood vessels are rarely recognized. We report two such cases; one showed the radiological and histological appearances of a combined lipoma and an arteriovenous malformation, the other the appearances of a lipoma with a prominent capillary component. Computed tomography did not give any indication of their vascular nature, but surgery was complicated by intra- and postoperative haemorrhage.
