Falcine meningiomas (FMs) are defined as meningiomas arising from the falx, covered by the overlying brain parenchyma, and not involving the superior sagittal sinus (SSS). FMs together with parasagittal meningiomas represent the second most common location of intracranial meningioma. Clinical presentation depends on the dimensions and location of the FM. Surgery for FM removal deserves several considerations related to bridging veins, anterior cerebral artery branches, arterial feeders, SSS involvement, FM locations, and FM dimensions. In this chapter the principal aspects influencing surgical strategy are analyzed together with approaches and management.
大脑镰脑膜瘤（FMs）被定义为起源于大脑镰、被覆盖其上的脑实质所包绕且不涉及上矢状窦（SSS）的脑膜瘤。大脑镰脑膜瘤与矢状窦旁脑膜瘤一起，是颅内脑膜瘤第二常见的发病部位。临床表现取决于大脑镰脑膜瘤的大小和位置。切除大脑镰脑膜瘤的手术需要考虑多个因素，包括桥静脉、大脑前动脉分支、供血动脉、上矢状窦受累情况、大脑镰脑膜瘤的位置以及大小。在本章中，将分析影响手术策略的主要方面，并介绍手术入路和治疗方法。
