Radio-graphical Features of Gliosarcoma on Computed Tomography and Magnetic Resonance Imaging

Gliosarcoma is a rare type of glioma, a cancer of the brain that comes from glial, or supportive, brain cells, as opposed to the neural brain cells. Gliosarcoma is a malignant cancer, and is defined as a glioblastoma consisting of gliomatous and sarcomatous componentsThe aim of the study is to characterize the radiographic features of gliosarcoma, such as existence nature, content and appearance and enhancement on Computed Tomography and Magnetic Resonance Imaging. And also to find out which is the most effective imaging method to diagnose and categorize gliosarcoma. Fifteen patients were studied retrospectively from the PACS system of CT Scanner and MRI using the protocol of imaging of the head.The study reveals that majority(93.3%) of the gliosarcoma were single. About 80 percent of the gliosarcoma had both solid and cystic components. All fifteen tumors appeared to be relatively well demarcated from the surroundin normal or edematous brain parenchyma. On T2-weighted image eight shows of hyperintensity and isointensity.The study concludes that Gadolinium enhanced Magnetic Resonance Imaging is more accurate than plain MRI, plain CT, Contrast Enhanced CT in defining the margins of Gliosarcoma.
