title: Metastatic ependymoma of the sacrum.
abstract: Ependymomas originating in the sacrum or extraspinal parasacral soft tissues are rare tumors. The majority are of the myxopapillary type and may be locally destructive. Even though metastases are not uncommon in retrosacral ependymomas, they have been rarely described in intrasacral locations. A case is reported of a large intrasacral ependymoma with metastases to several vertebrae. Radiologic and pathologic studies are presented. Treatment options are discussed.
