Ependymal cells may be found within the coccygeal ligament as well as in heterotopic positions and therefore ependymomas may rarely occur in extraspinal locations. Although the cauda equina is the most common location, less than 5% of all spinal ependymomas occur extradurally in the sacrococcygeal region. We report a case of extraspinal myxopapillary ependymoma arising in the subcutaneous soft tissue posterior to the sacrococcygeal region and review the relevant literature.
室管膜细胞可见于尾骨韧带内以及异位位置，因此室管膜瘤很少发生于脊柱外部位。虽然马尾是最常见的发病部位，但在所有脊柱室管膜瘤中，发生于骶尾区域硬膜外的不到5%。我们报告1例发生于骶尾区域后方皮下软组织的脊柱外黏液乳头型室管膜瘤病例，并复习相关文献。
