Intrathoracic dural ectasia mimicking neurofibroma and scoliosis

Angular thoracic scoliosis combined with dural ectasia and foraminal enlargement is reported in a patient with neurofibromatosis. The dural cyst was resected through a high thoracic approach and the scoliosis dealt with by posterior spinal fixation with Modulock instrumentation. Follow up after 12 months showed no neurological deficit and no progress of the scoliosis.
