Extradural myxopapillary ependymoma with sacral osteolysis--a case report.

Extradural ependymomas arising from filum terminale externa in the sacrococcygeal region are very rare. Since 1937, out of 58 cases reported in English literature, only 13 cases of tumor located presacrally in the retrorectal space, have been reported. The authors report a 38 yrs old male with a primary ependymoma of the sacrococcygeal region causing extensive sacral destruction.
