  • Figure 1
    Double aortic arch - chest radiograph

    A mediastinal abnormality is seen in this chest radiograph performed in the emergency department.

     
    Area of Interest: Mediastinum; Imaging Technique: Conventional radiography; Procedure: Education; Special Focus: Congenital;
     
     
  • Figure 2
    Double aortic arch - CT
     

    The right and left subclavian and carotid arteries appear symmetrical in the upper mediastinum.

     
    Area of Interest: Mediastinum; Vascular; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    The right arch is larger, extends more cephalad and is more posterior than the left arch.

     
    Area of Interest: Mediastinum; Vascular; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    The ascending aorta is seen to divide into right and left arches, the right arch being larger, higher and more posterior than the left arch.

     
    Area of Interest: Mediastinum; Vascular; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    The ascending aorta is seen to divide into right and left arches.

     
    Area of Interest: Mediastinum; Vascular; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    In this case, the left arch is joining the right arch to form the descending aorta, which is not the most common appearance.

     
    Area of Interest: Mediastinum; Vascular; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;

    The descending aorta courses slightly on the right side of the midline, which is not the most usual appearance.

     
    Area of Interest: Mediastinum; Vascular; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;
     
     
  • Figure 3
    Double aortic arch - coronal view

    Coronal MIP view shows the right arch larger and more cephalad than the left. Note also the symmetric appearance of the supra-aortic vessels, and the descending aorta with a course slightly to the right side.

     
    Area of Interest: Mediastinum; Vascular; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Congenital;
     
     
  • Figure 4
    Double aortic arch - volume rendering

    Volume rendering view shows the right arch larger and more cephalad than the left arch, and the symmetric appearance of the supra-aortic vessels.
