Legionnaire's Disease Presenting With the Legionella Triad (Pneumonia, Rhabdomyolysis, and Renal Failure) and Cardiac Complications.

Legionella pneumonia is well-characterized as a cause of atypical, community-acquired pneumonia in susceptible individuals. In recent years, extrapulmonary manifestations, including an emerging triad of Legionella pneumonia, rhabdomyolysis, and renal failure, have been identified. Here we report a case of Legionnaire's disease that presented non-classically, with subclinical pneumonia and non-ST elevated myocardial infarction (NSTEMI). Although he received early treatment with antibiotics, he developed the Legionellatriad during admission. He had several episodes of cardiopulmonary decompensation during his hospital course, eventually ending in his passing. This case serves to highlight the importance of early identification and intervention in regard to extrapulmonary Legionella infection.
