CTICasesAdenocarcinoma localized with Indocyanine Green
Imaging findings
CT chest shows a screen-detected, subsolid cystic nodule that grew over a year. A pre-operative CT-guided injection of indocyanine green (ICG) mixed with methylene blue shows localized ground-glass opacity, allowing fluorescence-guided wedge resection of a biopsy-proven adenocarcinoma.
Key takeaways
Pre-operative localization of subsolid nodules is essential for successful video-assisted thoracoscopic surgery (VATS). Indocyanine green (ICG) injection is a novel, effective method where immunofluorescent lighting allows the surgeon to visualize the target area without the risk of wire displacement or rapid dye clearance.
