Abstract
A 72-year-old man with a history of tuberculous pleuritis at the age of 19 presented with exertional dyspnea for 6 months. A right lower opacity in the chest roentgenogram had been pointed out since he was 61 years old. The mass was 19 cm at the maximum diameter and compressed the mediastinum. With a diagnosis of chronic expanding hematoma of the thorax, the patient underwent extirpation of the hematoma with the whole capsule. Since the hematoma adhered strongly to the lung and diaphragm, it was removed with the combined resection of the middle and lower lobe of the lung and the hemidiaphragm, which was reconstructed with a polypropylene mesh. The postoperative course was uneventful. Exertional dyspnea was resolved with improved pulmonary function.
