概念及概况 早在1938年Cushing等为颅内多发性脑膜瘤(以下称多发性脑膜瘤)下了定义,是指2个以上相互分离的脑膜瘤,但不包括弥漫性脑膜瘤病和多发性脑膜瘤合并神经纤维瘤病。Levin等认为病人在同一时期颅内生长2个或多个脑膜瘤称之为多发性脑膜瘤。Geuna等把多发性脑膜瘤分为三种:共时性多发性脑膜瘤;异时性多发性脑膜瘤;合并神经纤维瘤病的多发性脑膜瘤,但认为真正的多发 Concepts and Overview As early as 1938, Cushing et al. Defined intracranial multiple meningiomas (hereinafter referred to as multiple meningiomas) as two or more meningiomas separated from each other but excluding diffuse meningiomas and multiple Meningioma with neurofibromatosis. Levin, etc. think that patients in the same period of intracranial growth of 2 or more meningiomas called multiple meningiomas. Geuna and other multiple meningiomas are divided into three types: Synchronous multiple meningiomas; Synchronous multiple meningiomas; Multiple neurofibromatosis with meningioma, but that the real multiple
