Abstract The differentiation of apparent gastric wall thickening due to incomplete gastric distention from true pathologic wall thickening can be difficult on computed tomographic (CT) scanning. We have observed a transition in gastric wall thickening that is often present at or slightly above the gastric air-fluid or air-contrast level. The apparently thickened gastric wall in the dependent portion of the stomach undergoes an abrupt change to normal thickness at or above the air-fluid level. Review of CT scans in 259 patients without known or suspected gastric pathologic conditions revealed this finding, termed the “gastric air-fluid sign,” in 57 patients (22%). While not considered diagnostic, the presence of this sign may allow for a greater degree of confidence in the CT assessment of gastric wall thickening in an appropriate clinical setting.
