Abstract: The ductus arteriosus has functional importance in the fetal circulation. Aneurysm of the ductus arteriosus is characterized by saccular dilatation of the vessel. It is likely to develop in the third trimester due to changes in normal intima cushioning or alterations in elastin expression associated with connective tissue disease, but most cases have a benign course with spontaneous resolution. Prenatal diagnosis by ultrasound is possible and postnatal observation is justified due to possible late complications. Cases may be asymptomatic or complicated by a wide spectrum of complications, including spontaneous rupture, erosion, thromboembolism, and compression of adjacent structures. We report a prenatal diagnosis of aneurysm of ductus arteriosus. It was diagnosed at 33 weeks as a dilated vascular structure, 11 millimeters in diameter, connecting the descending aorta to the pulmonary artery. The Doppler image showed turbulent flow within this structure confirming the diagnosis. After spontaneous delivery, a structure compatible with aneurysm of the ductus arteriosus was found on the first day of postnatal life, which was then completely closed on the fifth day
