3D images show multiple anomalous variants of the aortic arch:
1. Right and Left CCA are seen arising from aortic arch as a common trunk.
2. Right subclavian artery is seen arising from junction of the aortic arch and descending aorta coursing in superior mediastinum posterior to the esophagus - aberrant right subclavian artery.
3. Left vertebral artery is seen arising from aortic arch proximal to the left subclavian artery
