Findings of computed tomography (CT) and 18F–fluorodeoxyglucose (18F–FDG) positron-emission tomography/computed tomography (PET-CT). a A transverse plane of an enhanced CT scan shows an intraluminal mass in the lower esophagus, which is well-defined without infiltration of the surrounding tissue (arrows). b 18F–FDG PET-CT scan shows 18F–FDG uptake at the same lesion of the lower esophagus; the SUV max of the lesion is 3.1 (arrows)
