title: Myxopapillary ependymoma of the ischioanal fossa.
abstract: Ependymomas outside the confines of the cranium and spinal cord are rare. Direct extension into the soft tissues of the sacrococcygeal area may occur from a primary ependymoma of the spinal cord, cauda equina or filum terminale. Alternatively they may occur as a primary pre-sacral, pelvic and abdominal tumour, or as a primary tumour of the skin and subcutaneous tissue of the sacrococcygeal area without any demonstrable connection with the spinal cord. The Authors report a case of myxopapillary ependymoma of the ischioanal fossa, demonstrated by MRI. To our knowledge, our case is the first lesion reported at this site.
