The right lung is hypoplastic, as is the right pulmonary artery. In addition, anomalous pulmonary venous drainage of the right upper and middle lobes and much of the right lower lobe is seen extending into a large anomalous vein that joins the IVC.
The study demonstrates that although the heart is positioned in the right hemithorax, the cardiac looping is normal, with the left ventricle seen to lie to the left of the morphologic right ventricle. The right lung is hypoplastic, as is the right pulmonary artery. In addition, anomalous pulmonary venous drainage of the right upper and middle lobes and much of the right lower lobe is seen extending into a large anomalous vein that joins the IVC. Only a single vein is seen to enter from the right lower lobe into the left atrium.
In addition, an anomalous arterial structure is seem to extend from the upper abdominal aorta into the right lung base, likely supplying a sequestration. Finally, there is a common origin of the celiac axis and mesenteric artery, the so-called celiomesenteric trunk.
