Regression of ductus arteriosus aneurysm in a neonate demonstrated by three-dimensional computed tomography

We present a case of ductus arteriosus aneurysm in a neonate in whom the diagnosis was made by echocardiography, three-dimensional surface rendering computed tomography (CT) and was subsequently confirmed by angiography. Regression of aneurysm after indomethacin treatment was clearly demonstrated in a follow-up CT scan. To our knowledge, this is the first report of ductus arteriosus aneurysm and its regression detected by 3D surface rendering CT.
