  • Figure 2
    Computed Tomography
     

    CT shows the aortic aneurysm with an EVAR and a homogeneous and well-defined mass with irregular borders and spontaneous attenuation similar to the paraspinal muscles, wrapping the aorta anteriorly and laterally.

     
    Area of Interest: Abdomen; Arteries / Aorta; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms;

    Arterial phase CT shows preserved EVAR permeability and no signs of endoleak. The mass appears infiltrative, without mass effect on the surrounding structures such as the arterial vessels seen anteriorly.

     
    Area of Interest: Abdomen; Arteries / Aorta; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms;

    Portal phase CT shows mild and homogeneous enhancement of the mass.

     
    Area of Interest: Abdomen; Arteries / Aorta; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms;

    The enhancement of the mass is homogeneous and progressive, peaking in the late phase CT.

     
    Area of Interest: Abdomen; Arteries / Aorta; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Aneurysms;

    Arterial phase CT with coronal reformation.
