Clear Cell Ependymoma of Spinal Cord:A Case Report

Clear cell variant of ependymoma is almost exclusively located in the supratentorial region. Only few cases of this tumor that located in the spinal cord have been reported. Here we report one caseof intramedullary clear cell ependymoma of the lumbar spinal cord. In microscopic examination,the tumor cells were round to oval with moderate amounts of clear cytoplasm and centrally locatedlarge nuclei, resembling oligodendroglioma. Typical features of ependymoma, such as ependymalclefts, perivascular pseudorosettes, as well as nuclear pseudoinclusions and grooves were identified.Albeit being rare, clear cell ependymoma could be mentioned in differential diagnosis of clear celltumors in this area.
