Angiolipoma intracraniano adjacente a aneurisma sacular cerebral: relato de caso e revisão da literatura / Intracranial Angiolipoma Associated with Cerebral Saccular Aneurysm: Case Report and Review of Literature

RESUMO

Angiolipomas são neoplasias benignas compostas por adipócitos maduros e proliferação vascular angiomatosa de rara ocorrência no Sistema Nervoso Central. É relatado o caso de angiolipoma em cisterna silviana adjacente a aneurisma sacular de artéria cerebral média. São discutidas as características imagenológicas do tumor e a possibilidade de uma origem comum com lesões vasculares intracranianas. Este é o primeiro caso relatado de angiolipoma intracraniano associado a aneurisma de artéria cerebral média.
