A Case of Comorbidity of Complicated Infective Endocarditis and Severe Pneumonia Due to Legionella Pneumophila

Legionella pneumophila infection can cause Legionnaires' disease, a severe form of pneumonia. Extrapulmonary manifestations of Legionella infections include myocarditis, pericarditis, and endocarditis. We present a rare case of pneumonia caused by Legionella pneumophila with a possible etiologic link to a recently recovered culture-negative infective endocarditis.
