Spinal intradural extramedullary teratoma is a rare condition that develops more commonly in children than in adults. It may be associated with spinal dysraphism. We report an exceptional case of adult-onset intradural extramedullary teratoma of the cervical spinal cord and bulbomedullary junction with no evidence of spinal dysraphism and no history of previous spinal surgery and/or lumbar puncture. The patient was a 38-year-old woman whose chief complaint was progressive installation of a tetraparesis. Magnetic resonance imaging showed a cystic tumor on both sides of the foramen magnum compressing the bulbomedullary junction. The tumor was totally surgically resected. The histopathological diagnosis was a mature teratoma.
脊髓硬膜内髓外畸胎瘤是一种罕见疾病，在儿童中比在成人中更常见。它可能与脊髓发育异常有关。我们报告一例罕见的成年发病的颈髓和延髓脊髓交界处硬膜内髓外畸胎瘤病例，该病例无脊髓发育异常证据，且无既往脊柱手术和/或腰椎穿刺史。患者为一名38岁女性，主要症状是进行性四肢轻瘫。磁共振成像显示枕骨大孔两侧有一个囊性肿瘤，压迫延髓脊髓交界处。肿瘤通过手术完全切除。组织病理学诊断为成熟畸胎瘤。
