Abstract
A 78-year-old male was admitted to a local hospital because of fever and sputum production. Chest x-ray revealed a pulmonary cavity of 10cm in diameter in the right lower lobe, which was diagnosed as a lung abscess. Although antibiotics were administered for two months, the pulmonary cavity and clinical symptoms did not improve. Sputum cytology revealed adenocarcinoma. He was referred to our hospital, and was diagnosed as having lung cancer with massive necrosis and infection. Right lower lobectomy was performed along with intraoperative drainage of the cavity, which showed a whitish, mucinous fluid. Pathologic examination revealed bronchioloalveolar carcinoma with mucin production. Three months later, multiple small cavities appeared as a recurrence in both lungs, and they changed into a thin-walled, bulla-like shadow on chest CT in both lungs 8 months later.
