Rugal folds

Last revised by Tom Foster on 20 May 2021

The rugal folds are the mucosal folds within the stomach that give the distinctive appearance on barium studies.

Rugal folds aid in increasing the volume of stomach without a significant change of the pressure within. They are comprised of both mucosa and submucosal layers. Normally the thickness is 3-5 mm. Increased thickness or nodularity suggests a pathological process.
