Rhabdomyolysis has been described as a rare sequela of severe infections by group A streptococcus related to toxic shock syndrome in adults. Streptococcal pharyngitis, on the other hand, has never been reported to cause rhabdomyolysis. We report a case of rhabdomyolysis in a child after an uncomplicated course of group A streptococcal pharyngitis. Although MRI of rhabdomyolysis from other causes has been described in a few case reports, this is a unique MRI description of its occurrence with streptococcal pharyngitis.
