Intradural extramedullary (IDEM) ependymomas occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 57-year-old woman with an IDEM ependymoma. She was referred for the evaluation of a 4-month history of increasing neck pain and muscular weakness of the left extremities. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an IDEM tumor with spinal cord compression. At the time of surgery, an encapsulated IDEM tumor without a dural attachment or medullary infiltration was noted, but the tumor capsule adherent to the spinal cord and root was left in place to minimize the risk of neurological sequelae. Histologic examination revealed a benign classic ependymoma. The post-operative course was uneventful and radiotherapy was performed. The patient showed an excellent clinical recovery, with no recurrence after 5 years of follow-up.
硬脊膜内髓外（IDEM）室管膜瘤非常罕见，关于其临床特征的报道很少。作者报告了一例57岁女性患有IDEM室管膜瘤的病例。她因颈部疼痛加重和左上肢肌肉无力4个月的病史前来接受评估。颈椎磁共振成像（MRI）显示一个IDEM肿瘤伴脊髓受压。手术时，发现一个有包膜的IDEM肿瘤，无硬脑膜附着或髓内浸润，但与脊髓和神经根粘连的肿瘤包膜留在原处，以尽量降低神经后遗症的风险。组织学检查显示为良性经典室管膜瘤。术后过程顺利，并进行了放疗。患者临床恢复良好，随访5年无复发。
