abstract: OBJECTIVE
  To report an influenza B infection with associated myocarditis and severe skeletal myositis.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Cardiac intensive care unit in a university-affiliated children's hospital.
  
  
  METHODS
  A 4-yr-old girl.
  
  
  RESULTS
  The patient was successfully supported with extracorporeal membrane oxygenation for profound myocardial dysfunction and a combination of plasmapheresis and continuous venovenous hemodialysis for rhabdomyolysis and acute renal failure.
  
  
  CONCLUSIONS
  This case provides a reminder that patients presenting with viral illness or myoglobinuria accompanied by renal failure, with or without associated myocarditis, may be demonstrating symptoms of influenza B.
