An adult case of eosinophilic pyloric stenosis maintained on remission with oral budesonide


We describe an isolated eosinophilic pyloric stenosis in a young female. She was referred for abdominal pain, fever, weight loss and eosinophilia. A sonographic examination revealed a concentric pyloric stenosis, with antral palsy and ascites. The endoscopy confirmed the diagnosis of eosinophilic infiltration of the pylorum. After a short course of systemic steroids, the patient was switched to oral budesonide, which effectively maintained a long term remission. Eosinophilic gastroenteritis limited to pylorum is exceptional in adults, and in our patient it was not associated with allergic other disorders. This case emphasizes the usefulness of sonografy for diagnosis and monitoring, and the clinical efficacy of oral budesonide.
