A 48-year-old man, who had worked as a welder for 30 years, was admitted to our hospital with bloody sputum. His chest CT scan showed diffuse centrilobular micronodules and fungus balls within cavities in the apices of both lungs. We diagnosed pulmonary aspergilloma associated with welder's lung in the apices of both lungs, by bronchoscopy. He was treated with oral antifungal drugs for 1 month, but he had massive hemoptysis. Bronchoscopy showed that the hemoptysis originated from the right upper lobe. We performed right upper lobectomy after right bronchial and intercostal arterial embolization. About 2 months after surgery, he had bloody sputum again. We then performed left bronchial and intercostal arterial embolization because bronchoscopy showed that the bloody sputum originated from the left upper lobe. His bloody sputum disappeared after the last embolization treatment. We report a rare case of pulmonary aspergilloma associated with welder's lung, with a discussion based on a review of the literature.
