Anomalous right superior and middle pulmonary veins. (a) Coronal oblique maximum intensity projection CT image. The right superior pulmonary vein is seen draining into the superior vena cava (arrow). Just inferior to this the right superior and inferior middle pulmonary veins are also seen draining separately into the superior vena cava/right atrium confluence (arrowheads). b Axial oblique MIP CT 5-chamber view, demonstrating a superior sinus venosus defect (black arrow), anomalous middle pulmonary vein (white arrowhead) and marked right ventricular dilatation secondary to the left-to-right shunt
