We describe a case of giant pulmonary aspergilloma in a 79-year old man. He had undergone an operation for pulmonary tuberculosis of the right lung at the age of 49 years. His chest ragiograph showed a large fungus ball in the right upper lung field. Taking his age and pulmonary condition into consideration, we performed a cavernostomy and fungus ball resection to prevent life-threatening hemoptysis. The postoperative course was satisfactory and without complication. Cavernostomy may be an alternative choice in high-risk aspergilloma patients.
