title: An unusual presentation of spinal dural arteriovenous fistula: A case report.
abstract: BACKGROUND
  Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence.
  
  
  METHODS
  Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out other possibilities.
  
  
  RESULTS
  A definitive diagnosis of arterio venous fistula was confirmed by clinical and MRI examination and demonstrated abnormalities compatible with dural arteriovenous fistula.
  
  
  CONCLUSIONS
  Dural arteriovenous fistula should be considered in patients with paresis in both lower extremities.
