title: Primary angiitis of the spinal cord presenting as a conus mass: long-term remission.
abstract: BACKGROUND
  Primary angiitis of the central nervous system (CNS) is a rare vasculitic disorder that typically involves the brain and, less frequently, the spinal cord without involvement of the blood vessels outside the CNS.
  
  
  METHODS
  We present a case of a 52-year-old woman who developed a conus syndrome linked to an enhancing mass of her lower thoracic spinal cord, lumbar cord, and conus. Spinal cord biopsy performed for diagnostic purposes in the setting of progressive neurological deficit confirmed angiitis of the spinal cord. Therapy with steroid and cyclophosphamide was associated with long-term (3 years) clinical and imaging remission of the lesion.
  
  
  CONCLUSIONS
  The prognosis of primary CNS angiitis is dismal with most cases progressing to death. Long-term remission is unusual. Aggressive therapy with steroid and cytotoxic agents may improve survival.
