Ductus diverticulum aneurysm associated with bicuspid aortic valve and dilatation of ascending aorta.

Saccular aortic aneurysm arising in the ductal region, known as ductus diverticulum aneurysm, is a rare anomaly. Due to potentially malignant evolution, recognition of radiological signs associated with this anomaly during the asymptomatic phase may be important in order to plan surgical intervention in time. We report an unusual case of ductus diverticulum aneurysm combined with bicuspid aortic valve, dilatation of ascending aorta, and coronary artery disease.
