A 11-year-old male was admitted to the our Paediatric Cardiology Unit for a cardiac murmur. Transthoracic echocardiography showed mild dilatation of the right atrium and the right ventricle with increased superior caval vein flow and minimum secundum atrial septal defect. This examination revealed two of four pulmonary veins draining into the left atrium. It was suspected supracardiac partial abnormal pulmonary venous return. Multidetector computed tomography (MDCT) was performed on a 64-detector-row CT scanner (Aquillon; Toshiba Medical Systems, Tokyo, Japan) for preoperative further evaluation of vascular abnormalities. After scanning, we transferred the MDCT data sets to an independent workstation (Vitrea, Toshiba) for postprocessing. CT angiography (CTA) confirmed that abnormal return of the right pulmonary veins connected to the dilated innominate vein, with subsequent continuation to the right superior vena cava (Fig.). In this malformation right pulmonary veins connect to the innominate vein with subsequent drainage to the right superior vena cava and to the right atrium. It is often difficult to detect the pulmonary vein confluence by echocardiography and catheter-based angiography. CT and MRI may be used to further delineate the cardiac anatomy. Several previous reports showed that CTA has some advantages when compared to other imaging modalities. It is a non-invasive technique. In addition, it has more spatial resolution than MRI. In conclusion, as the role of CTA as a imaging modality is increasing, rare congenital heart disease such as PAPVR need to be recognized on MDCT.
