title: Acute venous sinus thrombosis after chickenpox infection.
abstract: BACKGROUND
  Chickenpox is one of the classic childhood diseases. Recently chicken pox has been reported in adults with more severe systemic and neurological complications. Cerebral venous thrombosis (CVT) is a life threatening disorder if not treated in time. We report a patient with post varicella CVT as a rare complication of primary Varicella zoster virus.
  
  
  METHODS
  Vasculitic arterial infarction is known while venous stroke has rarely been reported with Varicella-zoster virus infection. Here, we report an immunocompetent 30 yr old male who developed chickenpox after contact with his daughter two month back. He presented with acute neurological deficit, one week after onset of skin lesion. MR venography revealed non-visualisation of left transverse sinus and left sigmoid sinus suggestive of venous sinus thrombosis.
  
  
  CONCLUSIONS
  Varicella infection is rarely associated with venous sinus thrombosis. Possibly hypercoagulable state produced by the infection or direct invasion of virus in venous endothelial wall with subsequent damage to endothelium leading to thrombosis could be the cause.
