Eosinophilic gastroenteritis with ileus and ascites

We report a case of eosinophilic gastroenteritis, which has features of the predominant subserosal type presented as an ileus and ascites. A 48-year-old Japanese woman was admitted to our hospital because of epigastralgia, lower abdominal pain and vomiting. She had a past history of allergic disorders. The computed tomographic scan revealed ascites, and marked wall thickening and dilatation of the intestine. This patient showed eosinophilic ascites without marked peripheral eosinophilia. Histologic examination demonstrated eosinophilic infiltrates did not predominate in the gastrointestinal tract. Conservative treatment of intravenous infusion of antibiotics and Ringer's solution was effective in this case.
