title: Posterior reversible encephalopathy syndrome in the emergency department: case series and literature review.
abstract: BACKGROUND
  Posterior Reversible Encephalopathy Syndrome (PRES) often has variable presentations and causes, with common radiographic features-namely posterior white matter changes on magnetic resonance (MRI). As MRI becomes a more frequently utilized imaging modality in the Emergency Department, PRES will become an entity that the Emergency Physician must be aware of and be able to diagnose.
  
  
  METHODS
  We report three cases of PRES, all of which presented to the emergency department of a single academic medical center over a short period of time, including a 53-year-old woman with only relative hypertension, a 69-year-old woman who ultimately died, and a 46-year-old woman who had a subsequent intraparenchymal hemorrhage.
  
  
  CONCLUSIONS
  PRES is likely much more common than previously thought and is a diagnosis that should be considered in a wide variety of emergency department patient presentations.
