Objective: The aim of this study was to demonstrate the changes of PDA aneurysm by performing a serial imaging study

Methods: A newborn was found to have a large ductus arteriosus by screening two-dimentional echocardiography (2DE) on the first day of life. A ductal aneurysm developed on the third day of life. A series of imaging studies including 2DE, three-dimentional echocardiography (3DE), three-dimentional CT (3DCT) and MRI had been performed.

Results: The large ductus arteriosus changed into a ductal aneurysm on the third day of life and thrombus was gradually formed inside the aneurysm leaving a small tract with blood flow. The small tract is still patent and we are still following up the patient.

Conclusions: 3DE and 3DCT enhanced our ability to image and understand the spatial relationship and changes of the PDA aneurysm anatomy by providing superior imaging and demonstrating the shape and surrounding structures of the PDA aneurysm.
