FIGURE 5. A 45-y-old woman with NPC 12 mo after concurrent chemoradiation therapy. (A) ¹⁸F-FDG PET scan shows an area of uptake (arrow) in the left hilar region. (B) Chest CT scan shows a small pulmonary nodule (arrow, top) in the left upper lobe and discloses another tiny nodule (arrow, bottom) in the right lower lobe. A follow-up CT scan 2 mo later showed definite enlargement at these 2 lung nodules, consistent with lung metastases.
