What symptom is least likely to be associated with a popliteal aneurysm?

A popliteal aneurysm typically affects blood flow in the lower extremities and can lead to various symptoms related to vascular insufficiency. Abdominal pain is least likely to be associated with a popliteal aneurysm because this type of aneurysm primarily affects the popliteal artery located behind the knee, and its symptoms manifest locally or in the leg rather than in the abdominal region.

The more common symptoms linked to a popliteal aneurysm include claudication, which is characterized by leg pain that occurs during exercise due to inadequate blood flow. Acute limb ischemia can also occur if the aneurysm becomes thrombosed or ruptures, leading to a sudden decrease in blood supply to the leg. Pain in the knee is another symptom often seen as the aneurysm can cause discomfort in that area due to proximity to the knee joint. Thus, abdominal pain does not typically correlate with this specific vascular condition, making it the least likely symptom associated with a popliteal aneurysm.
