Benign Schwannoma rarely involves the vertebral bodies extensively. Despite of huge amount of neoplastic mass and severe destructive bony changes, the neurologic deficits could not be discovered. The authors discussed the findings of plain X-rays, cervical CT, MRI, pathology as well as surgical procedure, and reviewed the literatures.

The authors have experienced a case of an arachnoid cyst within the cervical canal. The patient suffered from right upper extremity pain and numbness for 1 month. On cervical MRI, intradural extramedullary mass was detected. A total laminectomy of C5, C6 and C7 was performed. We could diagnose by radiological and pathological findings.
