ABSTRACT
A 56-year-old woman underwent a left upper lobectomy for primary lung adenocarcinoma. At 4 years and 5 months after the operation, she presented two localized ground-glass opacities (GGO) in the left lower lobe. Both were resected, and a diagnosis of adenocarcinoma was made. At 2 years and 8 months after the second operation, localized GGO appeared and grew in the remaining left lower lobe. Partial resection for the GGO was performed, and a diagnosis of cholesterol granuloma was made. Because there are no reports of cholesterol granuloma showing localized GGO in a CT scan, it is difficult to suspect cholesterol granuloma with GGO. Furthermore, it is more difficult to diagnose cholesterol granuloma with GGO in patients having a history of metachronous lung adenocarcinoma.
