title: Extraspinal ependymoma.
abstract: Two cases of extraspinal ependymoma are described. This is a low-grade tumor that recurs locally unless wide local excision is performed. It does metastasize, mainly to lymph nodes and lung. Its origin is likely from heterotopic ependymal cells called the coccygeal medullary vestige.
