A case of rhabdomyolysis associated with bacteremic pneumonia due to Staphylococcus aureus is reported. A 58-year-old man was admitted because of severe left lobar pneumonia, and presented myoglobinuria on admission. The serum creatine phosphokinase level was transiently elevated and myoglobinuria were disclosed. Sputum and venous blood cultures grew Staphylococcus aureus. Rhabdomyolysis has rarely been reported in cases of bacterial infection, especially those due to Staphylococcus aureus. This case might be an extremely rare case of rhabdomyolysis complicating Staphylococcus aureus bacteremia following severe left upper lobar pneumonia.
