Figure 3 (A) Oblique coronal image through a 3D dataset, showing an anomalous pulmonary vein formed by the right upper and right middle pulmonary veins that courses through the right thorax and enters the inferior vena cava below the level of the diaphragm (arrow). Despite the large field of view and the fact that the vessel crosses the diaphragm, the vessel’s course is clearly depicted. (B) Right lower lobe pulmonary vein enters the left atrium normally (arrow). The right pulmonary artery is identified by the open arrow.
