Which condition can manifest as multiple abdominal aortic aneurysms?

Behçet disease is an inflammatory condition that can lead to various vascular complications, including the formation of multiple abdominal aortic aneurysms. This condition is characterized by recurrent oral and genital ulcers and ocular involvement, but it also has systemic effects that can impact blood vessels. The inflammation associated with Behçet disease affects the vascular walls, making them more susceptible to aneurysms.

The pathophysiology behind the aneurysms in Behçet disease involves a vasculitis component, where inflammation can weaken the arterial wall over time, leading to aneurysm formation in large vessels like the abdominal aorta. This is evidenced by clinical findings that show a correlation between Behçet disease and a heightened risk of aneurysms.

Takayasu arteritis primarily affects large elastic arteries and is less commonly associated with multiple abdominal aortic aneurysms, as it tends to cause stenosis rather than aneurysm formation. Radiation vasculitis typically arises as a response to past radiation therapy and can cause vascular injury but is not well-known for causing multiple aneurysms. Relapsing polychondritis has a different pathophysiology and is not primarily associated with vascular complications leading to multiple aneurysms either.

Thus, Behçet disease
