title: Extraspinal ependymoma presenting as a subcutaneous mass posterior to the sacrococcygeal region. Case report.
abstract: Ependymal cells may be found within the coccygeal ligament as well as in heterotopic positions and therefore ependymomas may rarely occur in extraspinal locations. Although the cauda equina is the most common location, less than 5% of all spinal ependymomas occur extradurally in the sacrococcygeal region. We report a case of extraspinal myxopapillary ependymoma arising in the subcutaneous soft tissue posterior to the sacrococcygeal region and review the relevant literature.
