A case of spinal multiple extradural cyst is reported and reviewed. A 33-year-old male was admitted to the Osaka University Hospital. He had suffered from spastic paraparesis for the previous 8 months. On admission he couldn't walk by himself. A myelogram showed epidural masses in the thoracic region. Post-myelogram computed tomography showed a flattened and narrow spinal cord surrounded by the subarachnoid space, and large cysts located behind the spinal cord. A myelogram by direct puncture of the cyst defined three cysts. The patient was treated by removal of the three cysts and closure of the openings. The cyst wall was composed of dura mater and arachnoid membrane. About 30 days after the operation, he could walk unsupported, and sensory disturbances also diminished. The cysts, though communicating, appeared to have compressed the spinal cord.
