Barium studies in diffuse eosinophilic gastroenteritis.

We report the findings on barium examinations from 20 patients with eosinophilic gastroenteritis. Thickening of mucosal folds in the stomach (seven cases), small intestine (four patients), or both (two cases) was the most common finding. Nodular fold enlargement was present in the stomach in three cases and in the small intestine in four cases. One patient had discrete antral polyps. Multiple gastric erosions, to our knowledge not previously reported in eosinophilic gastroenteritis, were seen in two patients. Although the stomach and small bowel are most commonly affected, any portion of the gastrointestinal tract may be involved.
