title: Dural Arteriovenous Fistula Mimicking a Brainstem Glioma.
abstract: BACKGROUND
  Brainstem intracranial dural arteriovenous fistulas are extremely rare and can mimic a glioma at the time of presentation.
  
  
  METHODS
  We report a patient with an infiltrating brainstem lesion that finally revealed an intracranial dural arteriovenous fistula, with full neurological improvement after embolization.
  
  
  CONCLUSIONS
  A careful radiological study looking for dilated vessels around the brainstem is necessary in the workup of an infiltrating brainstem lesion, in order to rule out intracranial dural arteriovenous fistula.
