Reflux Esophagitis Secondary to Chemotherapy Detected by Serial FDG-PET

Abstract

A 69-year-old man with colon carcinoma underwent serial fluorine-18 fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) scans for restaging and monitoring the treatment response. He was having symptoms of possible persistent reflux esophagitis following chemotherapy. Serial FDG-PET scans obtained during and after completion of chemotherapy revealed abnormal diffuse FDG uptake in the esophagus in all 3 PET studies. These findings of FDG-PET scans were suggestive of possible postchemotherapy reflux esophagitis.
