Pediatric eosinophilic gastroenteritis: report of one case.

Eosinophilic gastroenteritis is an uncommon disease of unknown cause found particularly in children. It is characterized by the infiltration of eosinophils into the wall of the gastrointestinal tract, peripheral eosinophilia, and chronic relapsing gastrointestinal disorder. This report describes a patient with serosal eosinophilic gastroenteritis presenting ascites and peripheral eosinophilia. The diagnosis of the eosinophilic gastroenteritis was supported by sonographic analysis and dramatic clinical response to prednisolone therapy.
