title: Primary intradural extramedullary ependymoma: report of two cases and review of the literature.
abstract: Primary intradural extramedullary ependymomas are very rare. They are called primary in this location as they do not have any connection with the central nervous system. They usually develop from an ectopic ependymal cell nest. To the best of our knowledge, only 10 cases have been described in the literature. We report two cases of large sausage-shaped intradural extramedullary ependymoma in the lumbosacral area.
