A CASE OF EOSINOPHILIC GASTRITIS WITH PYLORIC STENOSIS

Abstract

A 77-year-old woman was admitted to our hospital because of repeated episodes of vomiting and abdominal pain. Computed tomography revealed fluid collection in the stomach and diffuse wall thickening of the antrum. Upper gastrointestinal endoscopy revealed irregular gastric mucosa of the antrum with severe pyloric stenosis. Histological examination of biopsy specimens showed mucosal infiltration of inflammatory cells and eosinophils. We diagnosed the patient with eosinophilic gastritis. After steroid therapy, the irregular-appearing mucosa improved. The pyloric stenosis was treated with multiple endoscopic balloon dilations, and the symptoms of the patient improved. The patient continues to be observed with administration of steroids.
