Right upper and right middle pulmonary veins form a scimitar vein draining into the suprahepatic portion of the inferior vena cava at the level of the diaphragm above the IVC interruption. Right lower and left upper/lower pulmonary vein drains normally into the left atrium.
The IVC is interrupted and drains into the right SVC via azygous continuation. Hepatic veins drain to the suprahepatic portion of the inferior vena cava cephalic to the interruption.
MR confirms mild right lung hypoplasia and rightward mediastinal shift.
