Gliosarcoma is an unusual malignant neoplasm of the central nervous system. It shares the same clinical presentation, epidemiology and prognosis with glioblastoma multiforme. It is usually located within intraparenchymal compartment, especially in the supratentorial area adjacent to the cortical surface. Intraventricular location is extremely rare for gliosarcoma. We report a rare case of intraventricular gliosarcoma. The features of the tumor, as observed by computed tomography (CT), magnetic resonance imaging (MRI) are described, along with a review of the literature.
