A case of cervical dural ectasia in von Recklinghausen's disease is reported. A 36-year-old female was admitted to our hospital with complaints of hypesthesia in the extremities and gait disturbance. Plain cervical x-ray films showed dilated interpediculate distance and increased A-P diameter of the cervical spinal canal. Myelography showed abnormally dilated subarachnoid space at C4-C7 level. Metrizamide CT scan also revealed abnormally dilated subarachnoid space, which was at the ventral site of the spinal cord. No tumors, arachnoid cysts, syringomyelia were noticed. From the above-mentioned radiological findings, dural ectasia in von Recklinghausen's disease was suggested. In the discussion, it was emphasized to consider dural ectasia in the differential diagnosis of the dilated spinal canal.
报告1例冯雷克林霍增氏病（神经纤维瘤病）合并颈椎硬膜扩张症。一名36岁女性因四肢感觉减退和步态障碍入院。颈椎X线平片显示椎弓根间距增宽，颈椎管矢状径增大。脊髓造影显示C4 - C7水平蛛网膜下腔异常扩张。甲泛葡胺CT扫描也显示蛛网膜下腔异常扩张，位于脊髓腹侧。未发现肿瘤、蛛网膜囊肿、脊髓空洞症。根据上述影像学表现，提示为冯雷克林霍增氏病合并硬膜扩张症。在讨论中，强调在诊断椎管扩张时应考虑硬膜扩张症以进行鉴别诊断。
