  • Figure 1
    Postcontrast Computed Tomography – Angiography axial image

    An aberrant right subclavian artery (arteria lusoria) which originates from the aortic arch, crosses the midline between the spine and the oesophagus.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 2
    Postcontrast Computed Tomography – Angiography axial image

    Arteria lusoria crosses the midline between the spine and the eosophagus. Both common carotid arteries originate from a common trunk. There is no abnormality of origin of the left subclavian artery.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 3
    Postcontrast Computed Tomography – Angiography coronal image

    Arteria lusoria originates from the aortic arch, crosses the midline between the spine and the oesophagus to reach the right side.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 4
    Postcontrast Computed Tomography – Angiography axial image

    Truncus bicaroticus gives rise to the right common carotid artery and the left common carotid artery associated with arteria lusoria.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 5
    CT angiogram with 3D reconstruction

    Three branches originate from the aortic arch: truncus bicaroticus (who gives rise to the right common carotid artery and the left common carotid artery), arteria lusoria and the left subclavian artery.
