title: Herpes Simplex Virus Type 2 Encephalitis as a Cause of Ischemic Stroke: Case Report and Systematic Review of the Literature.
abstract: OBJECTIVE
  Our objective is to describe a patient who developed an ischemic stroke as a complication of herpes simplex virus type 2 (HSV-2) encephalitis and to review the literature.
  
  
  METHODS
  A 45-year-old immune-competent Caucasian man presented with a 24-hour history of confusion and fever, and following clinical and laboratory examination was diagnosed with HSV-2 encephalitis. However, the brain magnetic resonance imaging also showed an acute ischemic infarct in the left frontal lobe corresponding to vascular territories of middle cerebral artery branches. Further screening failed to identify any other cause of the stroke. A systematic literature search was conducted in February 2015 using the PubMed database.
  
  
  RESULTS
  Six more cases of herpes simplex virus (HSV) central nervous system (CNS) infection that developed a definite ischemic stroke as a complication of the infection were identified.
  
  
  CONCLUSIONS
  Ischemic stroke, although infrequent, can complicate the evolution of herpes simplex meningitis or encephalitis. Clinicians should include HSV CNS infection as a possible cause of ischemic stroke, especially in young patients with ischemic stroke of unknown etiology.
