title: [A case of posttraumatic spinal pseudomeningocele which caused spinal cord compression 20 years after injury].
abstract: We reported an extremely rare case of posttraumatic spinal pseudomeningocele which caused spinal cord compression 20 years after getting injury, and demonstrated that sequelae of an injury may occur many years after the original wound. A 39-year-old man, who got left cervical root avulsion due to a traffic accident when he was 17 years old, began to complain of progressive muscle atrophy and weakness of left lower extremity 1 year ago. Myelography demonstrated pseudomeningocele at left C6-C8 level, and MRI and CT myelography revealed that the pseudomeningocele extends through the intervertebral foramen and compresses the spinal cord to the right side in the spinal canal. Bilateral functional compression of spinal cord dorsal and lateral column was also verified with SEP and MEP electrophysiologically.
