FIGURE 1. Hemoptysis and residual mass 9 mo after radical chemoradiotherapy for left upper lobe NSCLC suggested local relapse despite partial CT response between baseline (A) and posttreatment (B) scans. Representative transaxial (C), sagittal (D), and coronal (E) planes of PET scan showed low-grade pleural changes consistent with postradiotherapy effects but no evidence of recurrent disease. Palliative radiotherapy was cancelled, and patient remained well >12 mo after PET without evidence of active disease.
