Falcine meningiomas

Abstract

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.
