Massive hemorrhagic ascites: A rare presentation of eosinophilic gastroenteritis

摘要

According to Klein’s classification system, the symptomatology of eosinophilic gastroenteritis (EG), a rare disease, differs based on the affected tissue layer. Patients with subserosal EG often have peritoneal effusion. Hemorrhagic ascites due to EG is extremely rare and has not been reported in the literature. Here, we report a 57-year-old woman with EG and massive hemorrhagic ascites. Laboratory investigations showed elevated peripheral eosinophils with significant eosinophilia (65.6%). Ultrasonography showed massive abdominal ascites. Abdominal paracentesis revealed hemorrhagic peritoneal fluid and microscopy showed predominant eosinophils. Upper gastrointestinal endoscopy revealed erosions, exudates, and mucosal rings in the duodenal mucosa; histological examination indicated eosinophilic infiltration. EG presenting with hemorrhagic ascites was diagnosed by histologic examination of eosinophilic infiltration. She was empirically treated with ketotifen 1 mg bid po with rapid resolution of ascites and a remarkable decline in peripheral eosinophil counts. Clinicians should consider the differential diagnosis of unexplained hemorrhagic ascites.
