Rare case of rapidly reaccumulating ascites

Eosinophilic ascites is a rare type of exudative ascites most commonly caused by eosinophilic gastroenteritis. Here, a 57-year-old man presents with sudden-onset abdominal distension associated with nausea, vomiting and decreased appetite for 10 days. Physical examination revealed significant abdominal distention and fluid wave. Initial labs showed leucocytosis and mild peripheral eosinophilia. Imaging of his abdomen revealed severe ascites, no features of cirrhosis and diffuse inflammatory changes involving the jejunum and ileum. Diagnostic paracentesis showed exudative, ascitic fluid with predominant eosinophilia. Cytology of the ascitic fluid and blind biopsies taken during oesophagogastroduodenoscopy and enteroscopy were both negative for malignancy. The ascites reaccumulated rapidly, requiring five rounds of large-volume paracentesis during hospitalisation. Empiric treatment for suspected eosinophilic gastroenteritis with intravenous steroids improved and stabilised the patient's ascites for discharge. Parasitic workup resulted positively for Toxocara antibodies on ELISA. On 2-week outpatient follow-up, a course of albendazole resolved all gastrointestinal symptoms.
