Spinal MR is commonly u sed to assess the intraspinal contents prior to surgery for scoliosis. We report a case of neurofibromatosis I with dysplastic scoliosis whi ch demonstrated an extradural mass on MR. Subsequent CT scan showed th e presence of dislocation of the adjacent costovertebral articulation, with herniation of the rib head into the spinal canal.
