(A) ¹⁸F-FDG PET/CT in the axial plane and whole body maximum-intensity projection images, demonstrating abnormal FDG uptake in a left upper lobe tumor (SUV_max, 17.4) and the SUV_max of the mediastinal lymph node, 21.7. (B) Hematoxylin and eosin-stained tissue indicating adenocarcinoma features. Magnification, ×100. (C) Polymerase chain reaction confirmation of the EGFR wild-type.
