A staging positron emission tomography with computed tomography (PET/CT) scan revealed irregular thickening of the middle-third of the esophagus, consistent with esophageal mass seen on endoscopy (Figure 2).
PET/CT (coronal view): (a) intense fluorodeoxyglucose uptake in the region of the esophageal mass (arrow) and (b) complete resolution of fluorodeoxyglucose uptake in esophagus.
