Postoperative cervical pseudomeningocele as a cause of delayed myelopathy.

A spinal cord-injured patient developed progressive myelopathy 6 months after operative decompression of the cervico-medullary junction. At the time of the initial operation, the dura mater had been left open. A computed tomographic body scan revealed a cervical pseudomeningocele, which was repaired surgically. After operation, there was reversal of the patient's progressive neurological dysfunction.
