X-ray and CT presentation of advanced gastric carcinomas of different locations

Abstract

We presented the X-ray and CT findings characteristic for gastric cancers of different localizations (localized in different parts of the stomach). Particularly, esophagogastric junction (EGJ) carcinomas and antral carcinomas are singled out, as two localizations of gastric cancer that we usually meet in everyday clinical and radiological practice, and which have completely different radiological presentation. Advanced carcinomas of esophago-gastric junction, whose incidence is on the rise, usually affect the distal segment of the esophagus, cardia, and proximal part of the stomach, in different proportions. Siewert's, and the Japanese classification of these tumors are listed. Due to the involvement of the distal esophagus, scanning region, besides the abdomen, should be expanded to the chest. Advanced cancer of the antral part of the stomach is presented by the X-ray as a fungating, infiltrative, or combined form, often capturing the entire wall circumference. Possible infiltration of the left liver, the body and neck of the pancreas, colon and anterior abdominal wall should be estimated by CT.
