[Sacrococcygeal ependymoma. Review of the literature apropos of a personal case]. / Ependymome sacro-coccygien. Revue de la littérature à propos d'un cas personnel.

The authors report a personal case of sacro-coccygeal ependymona, the 11th known at the present day after a review of the literature. They describe the anatomical and clinical aspects of these tumors. The pre-operative diagnosis being most often one of common and benign lesion, like a pilonidal cyst, they emphasize the necessity of an histologic examination of every resected lesion of the sacro-coccygeal region.
