In 3.25% of 400 consecutive double-contrast upper gastrointestinal examinations, a prominent fold in the prepyloric gastric antrum that extends through the pylorus into the base of the duodenal bulb has been identified. Although the clinical significance of this fold is undetermined, endoscopic evaluation suggests it is a manifestation of chronic gastritis. This fold may simulate other entities, but can be distinguished by its characteristic features. Proper recognition may prevent unnecessary procedures such as endoscopy and biopsy.

    ABSTRACT: Gastritis is a group of inflammatory disorders that can be diagnosed radiographically. The optimum radiographic examination of the stomach is the biphasic-contrast technique, which includes the use of a medium-dense barium sulfate suspension and a hypotonic agent. Knowledge of the forms of gastritis, a careful application of biphasic-contrast technique, and a perceptive evaluation of information will help the radiologist to detect this entity with great frequency.

    ABSTRACT: We report a patient found to have a hypertrophied antral-pyloric fold on barium study, in whom CT demonstrated a smooth soft tissue mass on the anterior wall of the pre-pyloric antrum. When this finding is encountered on CT, a double-contrast upper GI study should be performed as the next diagnostic test. Endoscopy can probably be avoided if the barium study shows the typical findings of a hypertrophied antral-pyloric fold.

    ABSTRACT: To reassess the findings of a hypertrophied antral-pyloric fold on double-contrast barium studies. A search of radiologic files resulted in recovery of records of 1,796 patients with findings of antral gastritis on double-contrast upper gastrointestinal studies. According to radiologic reports, 40 patients had a hypertrophied antral-pyloric fold. The radiographs were reviewed retrospectively to determine the size, location, and morphologic features of the folds. Clinical, radiologic, and/or endoscopic follow-up data were obtained in 22 patients. All but two patients were symptomatic, and all but one responded to medical treatment. The hypertrophied antral-pyloric fold was located on the lesser curvature of the distal antrum in all patients and extended to the pylorus in 25 (62%) and into the base of the duodenal bulb in 15 (38%). The fold appeared as a smooth or slightly lobulated submucosal mass in 37 (92%) patients and as a plaquelike lesion in three (8%). Other radiographic findings of antral gastritis were present in 26 (65%) patients. In nine patients who underwent endoscopy, endoscopic and/or histologic findings of antral gastritis were present in five, but none had evidence of tumor. A hypertrophied antral-pyloric fold may be a sign of antral gastritis that is associated with characteristic radiographic findings. Endoscopy and biopsy may not be warranted when lesions with features typical of a hypertrophied antral-pyloric fold are seen on double-contrast barium studies.
