Eosinophilic gastroenteritis with ascites: an enigmatic diagnosis

A 41-year-old woman presented to the emergency department with a 1-month history of worsening abdominal pain, nausea, and vomiting. The patient gave no history of recent travel, previous abdominal surgery, or adverse reactions to any allergens. She had no past medical problems. However, 2 days before we saw her, the patient had a gastrointestinal endoscopy which found no abnormalities; gastroduodenal and colonic mucosal biopsies had also been reported as healthy.
