title: Clinical recognition of varicella zoster virus vasculopathy.
abstract: BACKGROUND
  It is important to recognize acutely evolving ischemic stroke attributable to reactivation of varicella zoster virus vasculopathy since antiviral agents are effective.
  
  
  METHODS
  Three cases seen by the author over a 2-year period are highlighted.
  
  
  RESULTS
  All patients presented with an evolving arterial or venous ischemia in the background of postherpetic neuralgia proceeding for weeks to months.
  
  
  CONCLUSIONS
  Chronic neuralgic pain in a dermatomal distribution of an evolving central nervous system vasculopathy is an important clue to its recognition.
