title: [Central prolapse of the Th12 -L1 nucleus pulposus with radiological signs of tumor of the conus medullaris].
abstract: The authors report a 42-year-old patient with excruciating pains felt in the interscapular and lumbar regions and both lower extremities without symptoms of root involvement. Myelography suggested presence of a tumour of the conus medullaris or epidural tumour in this area, at the Th12--L1 level. During the operation a central prolapse of the nucleus pulposus was found in the midline on the anterior wall of the vertebral canal below the longitudinal ligament. After operation all symptoms disappeared and the patient resumed work.
