title: Tanycytic ependymoma of filum terminale: a case report.
abstract: Tanycytic ependymoma is an uncommon but well-recognized variant of ependymoma. Here we report a case of tanycytic ependymoma occurring at the region of filum terminale in a 44-year male who presented with low backache, bilateral lower limb weakness and urinary incontinence. MR imaging in this patient showed a lesion that was composed of solid and cystic components and was suggestive of ependymoma. The filum terminale region is an extremely unusual location for the occurrence of tanycytic ependymoma. To the best of our knowledge this is the third case of tanycytic ependymoma occurring in the filum terminale region.
