I have Isolated this abdominal aortic aneurysm (AAA) using a Contract CT scan provided to me through a University course.
For your information here is a summary from AMBOSS about AAA:
Abdominal aortic aneurysm (AAA) is a focal dilatation of the abdominal aorta to more than 1.5 times its normal diameter. Men of advanced age are at increased risk for their formation; smoking and hypertension are also major risk factors. Observation, close follow-up, and reduction of cardiovascular risk factors are indicated for small aneurysms, whereas pronounced (> 5.5 cm) or rapidly expanding aneurysms require surgery. The prognosis is markedly worse if dissection or aneurysm rupture occurs. AAA rupture typically presents with sudden onset of severe tearing back or abdominal pain, a painful pulsatile mass, and hypovolemic shock, and should be managed with emergent surgery. All men between 65 and 75 years of age with a history of smoking should be screened once with an ultrasound to exclude an AAA.
