FDG PET/CT in a Case of Diffuse Esophageal Adenocarcinoma

Abstract

Esophageal cancer usually shows focal intense FDG uptake on FDG PET. Diffuse FDG uptake pattern of the esophageal cancer has been rarely reported. We describe FDG PET/CT findings in a case of esophageal adenocarcinoma showing diffusely intense FDG uptake mimicking esophagitis.

Drinking Large Volume of Hot Water May Cause Increased 18F-FDG Uptake in Esophagus

“…It is likely that the water significantly higher than normal temperature caused esophageal hyperemia, which leads to elevated FDG uptake of the esophagus. Various etiologies have also been well described in increased esophageal FDG uptake, including adenocarcinoma, 6 squamous carcinoma, 7 small cell carcinoma, 8 lymphoma, 9 reflux esophagitis, 10 fungal infection, 11,12 and esophagitis dissecans superficialis. 13 Our result indicates that drinking hot water before the PET/CT scan should be avoided in order to reduce diagnostic difficulty in the interpretation of increased esophageal FDG activity.…”

FDG PET/CT in a Case of Esophageal Extranodal NK/T-Cell Lymphoma, Nasal Type

“…Esophageal lymphoma may show focal, segmental as seen in this case, or diffuse activity on FDG PET/CT [8][9][10]. This case indicates esophageal lymphoma should be included in the differential diagnosis of the hypermetabolic esophageal diseases [11][12][13][14][15][16][17].…”
