EOSINOPHILIC GASTROENTERITIS MIMICKING IDIOPATHIC HYPERTROPHIC PYLORIC-STENOSIS

We report two infants with eosinophilic gastroenteritis (EG). This rar e disease can mimic the clinical symptoms and US appearance of idiopat hic hypertrophic pyloric stenosis (IHPS). US examination of the antrop yloric region with a high-frequency linear transducer can assist in th e differentiation of EG from IHPS, which is important because the ther apeutic approaches are completely different. Eosinophilic gastroenteri tis should be considered in the differential diagnosis of IHPS, especi ally when there has been an ineffective pyloromyotomy.
