  • Figure 1
    Pseudoaneurysm on CT

    Contrast-enhanced CT scan showing a 3-cm pseudoaneurysm (arrow heads), filled in part by an eccentric thrombus (arrows) and situated at the posterior of the left ascending ramus.

     
    Area of Interest: unknown; Imaging Technique: Pseudoaneurysm on CT;
     
     
  • Figure 2
    Psudoaneurysm on angiography

    Lateral view of selective left external carotid artery shows the pseudoaneurym (arrow heads) of the internal maxillary artery.

     
    Area of Interest: unknown; Imaging Technique: Psudoaneurysm on angiography;
     
     
  • Figure 3
    Superselective cannulation by microcatheter

    Digital subtraction angiography of the pseudoaneurysm is performed by injection of contrast medium from the microcatheter tip at the neck of the pseudoaneurysm. This shows the sac of the pseudoaneurym (arrow heads)...

    Angiography of postembolisation

    Post-embolisation angiogram from left common carotid injection shows complete obliteration of the pseudoaneurysm with preservation of the parent artery.
