title: Malignant spinal neurofibrosarcoma.
abstract: METHODS
  A report of a case of metastatic spinal neurofibrosarcoma.
  
  
  OBJECTIVE
  To document metastatic neurofibrosarcoma as a cause of spinal cord compression and to review the literature.
  
  
  BACKGROUND
  Three previously reported cases of metastatic neurofibrosarcoma of the spine were reviewed.
  
  
  METHODS
  The patient's clinical record and radiologic investigations as well as the result of a search of the English literature are reported. Magnetic resonance images, computed tomographic scans, and histology photomicrographs are displayed.
  
  
  RESULTS
  Paraparesis developed in this patient, due to a posterior extradural thoracic spinal cord compression by a neurofibrosarcoma believed to be metastatic from a neurofibrosarcoma of the femoral nerve.
  
  
  CONCLUSIONS
  Malignant spinal metastasis remains a rare complication of neurofibromatosis, with a very poor prognosis.
