An episode of acute decompensation of cervical myelopathy occurred after an injury without fracture of an os odontoideum associated with a compressive retro-odontoid cyst. The 51-year-old female patient presented Fränkel C, Nurick grade 4 neurological status and pyramid syndrome. The initial MRI demonstrated an intramedullary T2 hyperintense signal in the context of spinal cord narrowing. The retro-odontoid cyst demonstrates atlantoaxial instability related to the os odontoideum. Harms C1-C2 arthrodesis without laminectomy was performed and the cyst disappeared completely. Spinal cord decompression was thus obtained on the MRI taken 3 months later. Neurological recovery was complete and continued at 1 year.
一名51岁女性患者，因齿状突骨折伴压迫性齿状突后囊肿而受伤，随后发生了急性颈髓病失代偿发作。患者表现为Frankel C级、Nurick 4级神经状态和锥体束综合征。最初的MRI显示脊髓狭窄情况下髓内T2高信号。齿状突后囊肿显示与齿状突相关的寰枢椎不稳。进行了不做椎板切除术的Harms C1-C2关节融合术，囊肿完全消失。3个月后复查MRI显示脊髓减压成功。神经功能完全恢复，并在1年时持续改善。
