Aorto-esophageal fistula is a rare cause of upper gastrointestinal (GI) bleeding. The mortality rate is high if it is not diagnosed early. Hence, physicians should consider this condition, particularly in patients with unexplained or uncontrolled GI bleeding. In most cases, computed tomography angiogram is effective in detecting this condition, and emergent endovascular repair with aortic stent implantation can control the bleeding and can save the patient's life. Herein, we present a male patient with aorto-esophageal fistula bleeding; he was timely diagnosed but still died of massive gastrointestinal bleeding.
