A 54-year-old man was seen with massive hemoptysis. A posteroanterior chest radiograph revealed increased bronchovascular branching in the left hemithorax. Thoracic computed tomography showed a well-demarcated mass with uniform density confined to the apicoposterior and anterior segments of the left upper lobe. Fiberoptic bronchoscopy revealed a locus of bleeding in the apicoposterior segment of that lobe. Exploratory left thoracotomy confirmed the presence of a mass. The results of frozen section examination of a biopsy specimen were benign. The mass was resected by upper lobectomy. The definitive result of histopathological study of the mass was cavernous hemangioma. Very few cases of pulmonary hemangioma have been reported in the literature.
