Although the craniovertebral junction is one of the most common sites at which anomalies develop, spina bifida occulta of the axis (C-2) associated with cervical myelopathy is extremely rare. The authors present the case of a 46-year-old man who developed progressive tetraparesis caused by a cervical canal stenosis at the level of the axis. The spinal cord was compressed by an invaginated bifid lamina of the axis. The patient made a remarkable recovery after undergoing decompressive laminectomy of C-3 and removal of the bifid posterior arch of the axis.
尽管颅颈交界区是最常见的出现异常的部位之一，但枢椎（C-2）隐性脊柱裂合并颈椎脊髓病极为罕见。作者报告了一例46岁男性病例，该患者因枢椎水平的椎管狭窄而出现进行性四肢轻瘫。脊髓被枢椎内陷的双裂椎板压迫。患者在接受C-3减压椎板切除术和切除枢椎双裂后弓后恢复显著。
