title: A PRESsing dissection.
abstract: BACKGROUND
  Intracranial dissections have been associated with baroreceptor reflex failure. When this occurs labile hypertension may be observed with its own complications, including but not limited to the clinico-radiographic entity, posterior reversible encephalopathy syndrome (PRES).
  
  
  METHODS
  Case report and literature review.
  
  
  RESULTS
  We describe a case of carotid dissection resulting in PRES.
  
  
  CONCLUSIONS
  We believe failure of the baroreceptor reflex due to carotid dissection resulted in hypertension and subsequent posterior reversible encephalopathy syndrome.
