title: Osteolytic extra-axial sacral myxopapillary ependymoma.
abstract: The authors report an unusual case of sacral osteolytic myxopapillary ependymoma treated with curettage and radiotherapy. There is no evidence of recurrence 8 years after treatment. A review of the literature is presented on sacral ependymomas presenting with an osteolytic radiographic appearance (24 cases in 18 reports). The differential diagnosis with other sacral neoplasms is discussed.
