  • Figure 1
    CT-Angiography
     

    VR 3D reconstruction reveals the absence of left common carotid artery and separate origins of the left internal and external carotid arteries from the aortic arch.

     
    Area of Interest: Anatomy; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Congenital;

    Left internal carotid artery.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Congenital;

    MIP reconstruction shows the same findings.
