Hydatid disease is a parasitic infestation caused by the larval stage of Echinococcus. It can infest any part of the body; however, aortic hydatid disease is rare. Involvement of the abdominal aorta is usually due to embolization from cardiac hydatid cysts or direct invasion and can be present at intravascular or intramural locations. Aortic hydatid disease may present with fatal complications, such as anaphylaxis, pseudoaneurysm formation, systemic embolism, and arterial occlusion.
