Fistulas between an aneurysm branching off the abdominal aorta and the thoracic duct are rare. We report a case of aneurysmal-thoracic duct fistula diagnosed by angiography when aneurysm ruptured, and we successfully treated by catheter embolization. A 42-year-old man was referred to our hospital with a chief complaint of sudden back and chest pain. Computed tomography showed both post-mediastinal and retroperitoneal hematomas, with the aneurysm from the aorta being connected to the thoracic duct. After confirming the aneurysmal-thoracic duct fistula by angiography, we performed embolization of the aneurysm. The patient has remained well for 3 postoperative months, to date.
