Description

We report a case of thoracic scoliosis with dural ectasia and vertebral scalloping in neurofibromatosis type 1. A man, 36 years of age, had a history of back pain for several years. The diagnosis of neurofibromatosis was based on a histological examination carried out another hospital. He came to our hospital because of back pain previously at and evidence of a tumor in his right upper chest which had been found on a chest radiograph. On examination, he had multiple cutaneous cafe-au-lait spots and many cutaneous neurofibromata. There were no neurological abnormalities. Plane radiographs of his spine showed that a 13° right scoliotic curve extended from the third to eighth thoracic, and vertebral scalloping in the fourth to sixth thoracic. Posterior spinal instrumentation and fusion were performed from the third to ninth thoracic. A year after surgery, radiographs demonstrated no graft resorption and unchanged frontal aligment.
