  • Figure 1
    axial CT

    Axial CT showing the aortic arch (A) to the right side with a diverticular dilatation (red arrow) dorsal to the trachea. The last branch from the aortic arch is the left subclavian artery (blue arrow).

     
    Area of Interest: Cardiovascular system; Thorax; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Diagnostic procedure; Special Focus: Congenital;
     
     
  • Figure 2

    Coronal oblique reformation. Fig a. shows the aortic diverticulum (red arrow), from which the aberrant subclavian artery (blue arrow) originated.

     
    Area of Interest: Arteries / Aorta; Cardiovascular system; Thorax; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Diagnostic procedure; Special Focus: Congenital;

    Sagittal curved reformation shows the relation between the esophagus (white arrows) and the aortic diverticulum

    Post processing of the CT in frontal view, shows a right-sided aorta crossing over the right main pulmonary bronchus. Note: stenosis of the right ICA.

     
    Area of Interest: Arteries / Aorta; Cardiovascular system; Computer applications; Imaging Technique: CT-Angiography; Image manipulation / Reconstruction; Procedure: Computer Applications-3D; Contrast agent-intravenous; Diagnostic procedure; Special Focus: Congenital;

    Post processing of the CT in dorsal view. The distal portion of the aortic arch shows a diverticular dilatation, form which the left aberrant subclavian artery originated.
