Although very rare, a few cases of intradural extramedullary (IDEM) spinal tumor migration have been reported since Tomimatsu first reported a mobile schwannoma of the cervical cord in 1974. Schwannoma is a neurogenic tumor which originates from nerve sheath that it is relatively well-marginated tumor with little attachment or adhesion to surrounding tissue. Mobility of tumor in spinal canal sometimes can result in negative exploration at the expected area. We found three interesting cases in which different tumor locations observed in repeated magnetic resonance image (MRI) findings. All tumors were intradural and extramedullary schwannoma. We reviewed the literature about moving tumor in the spine through PUBMED search.
自1974年富松首次报告一例颈髓活动型神经鞘瘤以来，虽然硬膜内髓外（IDEM）脊髓肿瘤转移的病例非常罕见，但已有少数病例报道。神经鞘瘤是一种起源于神经鞘的神经源性肿瘤，它是一种边界相对清晰的肿瘤，与周围组织的附着或粘连较少。椎管内肿瘤的活动有时会导致在预期区域的探查结果为阴性。我们发现了三例有趣的病例，在重复的磁共振成像（MRI）检查结果中观察到肿瘤位置不同。所有肿瘤均为硬膜内髓外神经鞘瘤。我们通过在PUBMED上搜索，回顾了有关脊柱中移动性肿瘤的文献。
