FIGURE 1. PET/CT-based exclusion of suspected recurrent disease in site of increased ¹⁸F-FDG uptake localized to postoperative inflammatory changes. A 57-y-old man with a history of NSCLC showed equivocal CT findings in the area of right upper bronchus stump. (A) ¹⁸F-FDG PET coronal images show area of increased ¹⁸F-FDG uptake in upper aspect of right hilum (arrow). PET/CT (B, center) precisely localizes abnormal ¹⁸F-FDG uptake (B, left) to postoperative pleural thickening (arrows) adjacent to left atrium evident on CT (B, right). No ¹⁸F-FDG uptake was seen in area of equivocal CT findings in right upper bronchus stump. No further diagnostic procedures were performed. Patient had no evidence of disease for a clinical follow-up of 27 mo.
