case_images: fig3-11795468221116851
case_images: There is a large atrial septal defect resulting in a common atrium (Figures 3 and 4).
case_images: Three-dimensional virtual reconstruction shows a right-sided aortic arch, a large common atrium, and a left-sided superior vena cava.

case_images: fig5-11795468221116851
case_images: The common ostium of the left pulmonary vein drains into the posterior cardiac atrium (Figure 5), while the right superior and inferior pulmonary veins drain into the anterior cardiac atrium.
case_images: Axial CT shows a right aortic arch and left superior vena cava.

case_images: fig6-11795468221116851
case_images: The aortic arch is toward the right (Figure 6).
case_images: Three-dimensional virtual reconstruction shows a dominant right common carotid and a right subclavian artery arising from the aortic arch.

case_images: fig7-11795468221116851
case_images: There are 2 vessel arches; the first vessel is a dominant right common carotid and the second is a right subclavian artery that produces a dominant right vertebral artery (Figure 7).
case_images: Coronal CT shows a midline liver, a left-sided inferior vena cava, and fused adrenal glands seen on either side of the descending aorta.

case_images: fig8-11795468221116851
case_images: The abdominal CT showed the liver is midline (Figure 8), and there are clustered foci of splenic tissue in the right upper quadrant consistent with polysplenia (Figure 9). Highly vascular adrenal glands are observed to the right and left of the abdominal aorta, which appears fused (Figure 8).
case_images: Coronal CT shows right-sided polysplenia (white circle under right hemidiaphragm).
