FIGURE 1. Fibrotic scar (arrow) is present in right middle lobe on lung setting window CT image (A) of 42-y-old female breast cancer patient with past history of modified radical mastectomy, chemotherapy, and radiation therapy. PET/CT fusion images show small nodule in right upper lobe (B, arrow) and another in right middle lobe (C, arrow) without any 18F-FDG uptake on PET images (D and E). Follow-up lung CT images demonstrated no difference in size and shape of these nodules for >27 mo (image not shown), and nodules were presumed to be benign.
