An 86-year-old woman with a known abdominal aortic aneurysm underwent CT angiography with lower-extremity runoff for left-leg circulatory symptoms. Imaging demonstrated an aortocaval fistula, right atrial enlargement and dilated pelvic veins. The fistula was described as clinically asymptomatic and was treated by endovascular aneurysm repair eight days after detection. In the hours after the procedure, abdominal pain developed. CT angiography showed superior mesenteric artery occlusion and intestinal ischaemia. Palliative care was instituted, and the patient died the following day. This case illustrates incidental detection of an aortocaval fistula during imaging for another indication and the importance of assessing new abdominal symptoms after intervention.
