Heterotopic gastric mucosa in the duodenum: radiographic findings.
Heterotopic gastric mucosa in the duodenal bulb was detected by endoscopic examination in 25 adult patients and was confirmed by biopsy in 17 of these patients. The endoscopic findings were correlated with the radiographic features of the lesion on upper gastrointestinal barium studies. On radiographs, this entity usually presented as clusters of 1- to 3-mm plaques raised above the smooth and featureless duodenal mucosa; this was seen in 17 (68%) of 25 patients. A less frequent finding was patches of coarse nodular mucosa with superficial erosions or an ulcer crater (five cases [20%]). The heterotopic gastric mucosa was visible as polypoid masses in two patients and as prominent areae gastricae covering the base of duodenal bulb in another.
