Abstract
The presence of cartilaginous component in gliomas including ependymoma is a unique phenomenon. We herein report a further 8-year-old boy suffered from a tumor in the fourth ventricle that histopathologic evaluation proved its uncommun ependymoma with cartilage within the tumor tissue. Derivation of this mature chondrocytes is unkown and immunohistochemical labling for GFAP, EMA, cytokeratin and ki-67 could not support their possible origin from glial cells. Radiation role in chondroid metaplasia was rejected during this present case. At the end of article, we investigated cartilaginous ependymomas have more aggressive behavior than classic ependymomas.
