Primary intradural extraskeletal Ewing sarcoma is a very rare form of malignant neoplasm. Only few cases have been reported on the literature. Here, we report a case of a 14-year-old boy who had a chief complaint of pain and tingling in the right lower limb. The patient initially seemed to have a giant nerve sheath tumor but was eventually diagnosed with intradural extraskeletal Ewing sarcoma arising from the nerve roots of the cauda equine. The literature with regard to primary spinal intradural extraskeletal Ewing sarcoma is reviewed.
原发性硬脊膜内骨外尤文肉瘤是一种非常罕见的恶性肿瘤形式。文献中仅报道了少数病例。在此，我们报告一例14岁男孩，其主要症状为右下肢疼痛和刺痛。该患者最初似乎患有巨大神经鞘瘤，但最终被诊断为起源于马尾神经根的硬脊膜内骨外尤文肉瘤。本文对原发性脊柱硬脊膜内骨外尤文肉瘤的相关文献进行了综述。
