Background: Gliosarcoma refers to an uncommon astrocytic tumor of the central nervous system. These tumors include both glial and mesenchymal components by definition, and are extremely malignant. Gliosarcomas are particular to tumors with distinct gliomatous and sarcomatous constituents, and are distinguished from gliobastomas which have undergone mesenchymal metaplasia. Gliosarcomas encompass 2-8% of all glioblastoma cases and tend to occupy the supratentorial regions of the brain, especially the temporal lobe. Rare infratentorial lesions including the cerebellar hemisphere, intraventricular, and multi-focal tumors have also been reported. Accurate neuroimaging diagnosis is critical and diffusion tensor imaging (DTI) and spectroscopy can be useful to …
