No clinical suspicion but positive PET results. Anterior maximum-intensity-projection (A), axial CT (B), and axial PET/CT (C) images of 76-y-old man with T1N0 non–small cell lung carcinoma after right upper lobectomy and adjuvant chemotherapy. Clinically, patient was comfortable, with no complaints during follow-up at 3 y after completion of treatment. Restaging PET/CT study showed hypermetabolic focus (arrows) within left lower-lobe nodule, consistent with disease recurrence. Patient completed additional chemotherapy based on the results of this study.
