An Unusual Case of Eosinophilic Ascites with Pleural Effusion - A Rare Manifestation of Eosinophilic Gastroenteritis (EGE)

Eosinophilic gastroenteritis (EGE) is a rare disease characterized by tissue eosinophilia and can affect any part of the gastrointestinal (GI) tract from the oesophagus to the rectum, although the stomach and small intestine are sites most frequently involved. We hereby describe an unusual case of eosinophilic gastroenteritis affecting the stomach, small intestine, colon and rectum involving the mucosa and serosa. A twenty-one-year-old student presented with fever, diarrhoea, ascites and right pleural effusion. Total leucocyte count was high with marked eosinophilia. Ascitic and pleural fluid were exudates with low adenosine deaminase (ADA) levels and predominant eosinophils. Biopsy specimens of the stomach, duodenum, ileum, colon and rectum showed dense eosinophilic infiltration of lamina propria. Based on the constellation of clinical features and investigations, a diagnosis of EGE was made, and therapy with prednisone was started. Symptoms and peripheral eosinophilia rapidly resolved. It is thus imperative to diagnose this disease early and institute the necessary treatment.
