Influenza-B Associated Rhabdomyolysis and Acute Renal Failure.

We present a 15-year-old boy who developed severe rhabdomyolysis and acute renal failure following influenza B infection. His renal function was restored after appropriate therapy for rhabdomyolysis. Although rapidly progressive pneumonia, respiratory failure, and acute respiratory distress syndrome are the most common severe complications of influenza B infection, clinicians should be aware that influenza B may be complicated with rhabdomyolysis and acute renal failure in children.
