An unusually dilated right superior vena cava was noted. Abdominal sonography revealed asplenia with transverse liver. The pulmonary veins, however, were not well depicted due to poor acoustic window. Non-EKG gating multidetector computed tomography (Aquilion, Toshiba) using automatic tube current modulation was performed …
