Meningiomas and meningeal tumors

Abstract

Meningiomas are tumors arising from the arachnoidal coverings of the brain [45]. They are responsible for the vast majority of meningeal tumors and occur anywhere on the brain surface, including the skull base, and rarely also in the ventricular system. Other than meningiomas, hemangiopericytomas and meningeal sarcomas belong to the group of intrinsic meningeal tumors [45]. As with every other tissue, both metastases and lymphoma can also be found in the meninges. © 2010 Springer-Verlag Berlin Heidelberg.
