A 73-year-old woman suffered from neck pain, progressive m tor weakness and sensory disturbance in all extremities. Neuroradiological studies revealed a retro-odontoid mass with posterior compression of the upper cervical spinal cord. Decompression of the mass was performed via a postero-lateral transdural approach, and the patient exhibited marked improvement of the symptoms. Histological examination revealed that the mass was composed of degenerative cartilaginous tissue, consistent with disc material, but the lesion was not neoplastic. Retro-odontoid disc herniation causing cervical myelopathy is very rare. We primarily discuss the surgical management of retro-odontoid disc herniation.
一名73岁女性，出现颈部疼痛、四肢进行性肌无力和感觉障碍。神经放射学检查显示齿状突后方有一肿块，压迫上颈段脊髓。通过后外侧经硬膜入路对肿块进行减压，患者症状明显改善。组织学检查显示肿块由退变的软骨组织构成，与椎间盘组织相符，但该病变并非肿瘤性病变。齿状突后方椎间盘突出导致颈髓病非常罕见。我们主要讨论齿状突后方椎间盘突出的外科治疗。
