ABSTRACT
A 44-year-old man coughed up bloody sputum during a triathlon swimming competition. He immediately developed difficulty in breathing and was transported to our hospital by ambulance. A chest computed tomography scan showed multifocal, diffuse patchy ground glass opacities, lung field infiltration bilaterally, and nodular shadows along the respiratory tract. Although local bleeding was absent during bronchoscopy, the bronchoalveolar lavage fluid revealed diffused alveolar hemorrhage. Thus diffuse pulmonary hemorrhage was strongly suspected. Considering the medical history, clinical course, and examination results, we diagnosed the patient with exercise-induced pulmonary hemorrhage caused by strenuous exercise during the triathlon.
