Abstract
An unusual case of bilateral intratentorial lipomas with extension into Meckel's caves and the cerebellopontine angle is described. Surgical and histopathologic correlation demonstrate that the lipoma encased the trigeminal nerve in Meckel's caves. The origin of the lipoma from the anteromedial margins of the tentorium is discussed and correlated with a recently proposed theory for the development of intracranial lipomas.
摘要
本文描述了一例罕见的双侧幕下脂肪瘤，其延伸至梅克尔腔和桥小脑角。手术与组织病理学的相关性表明，脂肪瘤包裹了梅克尔腔内的三叉神经。文中讨论了脂肪瘤起源于小脑幕前缘的情况，并与最近提出的颅内脂肪瘤发育理论相关联。
