Localized emphysema is difficult to detect on normal thoracoscopy. Indocyanine green (ICG) was used to precisely delineate an emphysematous lesion using an infrared camera system in a 75-year-old woman with a large emphysematous lesion in the right lower lobe. Due to repeated infections of the emphysematous lesion, right basal segmentectomy for localized lung emphysema was performed. During surgery, ICG (0.5 mg/kg) was injected intravenously, and the emphysematous lesion was detected as a fluorescence defect. This method could be used for precise resection of large emphysematous lesions because it permits clear detection with a small amount of ICG.
