Peribronchiolar metaplasia with part-solid nodule showing faint 18F-fluorodeoxyglucose uptake: A case of difficult differentiation from early-stage lung adenocarcinoma
By Masato Kato and Satosi Yamamoto.
Abstract
症例は82歳，女性．右肺癌術後経過中にcomputed tomography（CT）検査で左肺下葉に15 mm大のpart solid noduleを認めた．4ヵ月後のCTでは腫瘍径に変化はなかったが，18F-fluorodeoxyglucose positron emission tomography（FDG-PET）で同部に淡い18F-FDG集積を認めたため，早期肺癌を疑い，胸腔鏡下区域切除術を施行した．病理検査では，細気管支肺胞腔は異型のない立方状あるいは扁平な上皮に覆われ，peribronchiolar metaplasia（PBM）と診断された．GGNを呈する孤立性のPBMは早期肺癌と鑑別すべき疾患と考えられた．
