Patient
male, 80 year(s)
 
 
  • Figure 1
    Abdominal ultrasound exam

    Incidentally, a huge abdominal aortic aneurysm with an intramural thrombus in the right posterior wall of the aorta is discovered by ultrasound study.

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound; Procedure: Observer performance; Special Focus: Dilatation;
     
     
  • Figure 2
    Contrast-enhanced CT angiography. Axial image sequences

    Infrarenal abdominal aortic aneurysm with a thrombotic ulcer in its wall is confirmed (A,B,C). There is arterialisation of the IVC and the iliac veins (C). Oedema around the aorta (D) indicates periaortitis.

     
    Area of Interest: Abdomen; Imaging Technique: CT-Angiography; Procedure: Contrast agent-intravenous; Special Focus: Fistula;
     
     
  • Figure 3
    CT angiography. Maximum intensity projection (MIP) reconstruction

    Coronal reconstruction image. Early enhancement of the inferior vena cava (IVC), synchronous and equivalent to that of the aortic lumen. In addition, it is showed the severe atherosclerosis of the aorta and great...

  • Figure 4
    CT angiography. Maximum intensity projection (MIP) reconstruction

    Sagittal reconstruction image (rotated). Directed communication between the two lumens through the aortic ulcer. Arterial opacification of the inferior vena cava indicates aortocaval fistula.
