Abstract
A large lung mass was incidentally found in a 68-year-old man. The chest computed tomography (CT) showed a lobulated mass in the right lower lung without enlargement of mediastinal lymph nodes. Well-differentiated adenocarcinoma was revealed by pathologic examination. Unexpectedly, a hypermetabolic lesion of standardized uptake value (SUV) 8.2 was noted in the gallbladder by fluoro-deoxy-glucose (18F-FDG-PET)/CT during staging work-up for lung cancer. A markedly thickened fundus of the gallbladder was shown on abdominal CT. Subsequent immunostainings for TTF-1 and CK-7 were negative suggesting the lung mass would not be primarily originating from the lung. Abdominal surgery was performed to remove the gallbladder mass, which was followed by right lower lobectomy of lung. An isolated lung metastasis from gallbladder cancer was confirmed although it is extremely rare.
