Fig 1 Computed tomographic scan images of a primary tumor in the right lower lobe and a pretracheal lymph node (A) before and (B) after induction chemotherapy. (A) Enlarged pretracheal lymph node (left) and nodular tumor in S6 (right). (B) Induction chemotherapy resulted in reduction of both the tumor (left) and pretracheal lymph node (right).

Fig 2 Fluorodeoxyglucose (FDG) positron emission tomographic images of lymph nodes (A) before and (B) after induction chemotherapy. (A) A single pretracheal lymph node diagnosed as pN2 by needle biopsy using endobronchial ultrasound, showing positive accumulation of FDG. (B) Multiple mediastinal and bilateral hilar lymph nodes showing positive accumulation of FDG.
