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.
