A case of cervical dural ectasia in von Reckling-hausen'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 inster-pediculate distance and increased A-P diameter of the cervical spinal canal. Myelography showed abnor-mally 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.
