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.
摘要
原发性硬脊膜外室管膜瘤非常罕见。它们之所以在这个位置被称为原发性，是因为它们与中枢神经系统没有任何联系。它们通常起源于异位室管膜细胞巢。据我们所知，文献中仅描述了 10 例。我们报告了两例位于腰骶部的大型香肠状硬脊膜外室管膜瘤。
