[A case of Legionnaires' disease associated with rhabdomyolysis]

Abstract

Legionnaires' disease is primarily a respiratory disorder, but recently several cases with extrapulmonary manifestations are reported. We report a case of Legionnaires' disease associated with pneumonia, diarrhea, central nerve disorders and rhabdomyolysis. The pathogenesis of rhabdomyolysis in Legionnaires' disease remains speculative. Endotoxin isolated from Legionella pneumophila may play a role in the pathogenesis of the myonecrosis. An additional factor that might contribute to rhabdomyolysis in this case is severe dehydration induced by diarrhea. Pneumonia with elevated CPK levels and myoglobinuria may suggest Legionnaires' disease.
