MRI of intracranial intraventricular lesions

Abstract

The MRI appearance of intraventricular neoplasms is often nonspecific, however knowledge of patient age and tumor location facilitates the formulation of a differential diagnosis. Imaging and pertinent clinical features of the following intraventricular neoplasms are reviewed: ependymoma, subependymoma, central neurocytoma, subependymal giant cell tumor, choroid plexus tumors, medulloblastoma, meningioma, chordoid glioma, rosette-forming glioneuronal tumor, central nervous system lymphoma, and metastasis.
