FIGURE 1.  A 49-y-old male patient with ESCC complained of discomfort of retrosternal burning after esophagectomy. PET/CT scan 4 mo after surgery demonstrated on fusion (A) and serial PET (B) images a positive focus suggestive of recurrence at esophagogastric anastomosis (SUV = 9.8); the lesion was shown to be FP by repeated endoscopy with biopsy.
