Patient Data

Age: 65 years
Gender: Male
  • marked aneurysmal dilatation of the infrarenal abdominal aorta measures about 6 cm in maximum AP diameter; this showed a large asymmetrical mural thrombus; it showed rather irregular internal luminal flow with multiple ulcerative plaques; in addition, this aneurysm showed marked extension into the right common iliac artery, which also contains a moderate asymmetrical thrombus (measured at 3.7 cm)

  • the above-described abdominal aneurysm showed discontinuous peripheral marginal atherosclerotic calcification with fissuring within the intramural thrombus seen along the left upper anterolateral part of the aneurysm. These signs are suggestive of an impending rupture

  • a marked ectasia of the left common iliac and external iliac arteries is also noted

  • colonic diverticulosis without evidence of diverticulitis

Case Discussion

An abdominal aortic aneurysm (AAA) typically defers to a condition where the diameter of the blood vessel reaches or exceeds 3 cm, and the risk of rupture is relatively low when the aneurysm measures less than 5 cm. AAA is often associated with other aneurysms, such as those in the popliteal region, and approximately 95% of these aneurysms fall into this category. Moreover, around 90% of abdominal aortic aneurysms occur in the infrarenal region of the abdominal aorta.
