case_images: CT chest revealed a 1.5 cm x 2.5 cm noncalcified pleural-based RUL nodule, a 1.1 cm calcified nodule in the left upper lobe, and an 8 mm noncalcified nodule in the right lower lobe (Figure 1). 18F-FDG PET/CT scan showed moderately increased uptake in all nodules with a maximum standardized uptake value (SUV) of 3.7 in the RUL nodule (Figure 2).
