 Ganglion cysts usually occur at the wrist or finger joints, and they rarely occur in the spinal region. We report a case of intradural extramedullary ganglion cyst in the cervical region that was diagnosed on the basis of the clinical and pathological findings. A 54-year-oldman was admitted to our hospital with a chief complaint of inability to elavate his left shoulder. MRI revealed an intradural extramedullary cystic lesion on the ventral side of the spine at the C2 level. The cyst was some distance away from the facet joints. A CT myelogram showed a concave deformity of the spinal cord due to compression by the cyst. C2 and C3 hemilaminectomy and total removal of the cyst, which contained clear and gelatinous fluid, was performed. The cyst was in contact with the anterior surface of the dura mater and had no connection with the facet joint. Histological examination showed that the cyst wall consisted mostly of fibrous connective tissue and had no synovial cell lining. The cyst was therefore diagnosed as a ganglion cyst. We also review previous reports and discuss the clinical and pathological features of spinal ganglion cysts.
