Chylous ascites is the accumulation of lymphatic fluid in the peritoneal cavity due to disruption of lymphatic drainage caused due to obstruction or trauma. We report a man in his 60s who was previously treated for diffuse large B cell lymphoma with radiation to bulky abdominal/mesenteric lymphadenopathy. He was later found to have recurrent chylous ascites several years later, requiring multiple paracentesis. Recurrent lymphoma was ruled out with negative cytology of peritoneal fluid as well as lymph node biopsy with no evidence of malignancy. We believe that the patient had obstruction of lymphatic drainage due to previous radiation therapy causing fibrosis. The patient underwent lymphangiography which did not visualise the central lymphatic duct within the abdomen raising suspicion for obstruction of the ducts secondary to previous radiation.
