case_images: Physical examination revealed a pulsatile tumor in the left popliteal region (Figure 1).
case_images: Lower limb computed tomography angiography with contrast showing left and right popliteal artery aneurysms. The left aneurysm has ruptured.

case_images: The patient underwent computed tomography (CT) with contrast, showing an enlarged left popliteal artery (LPA), with thrombus and contrast leakage delimited by a sac (Figure 2), findings characteristic of a ruptured left PAA measuring 14.4 centimeters at its greatest diameter.
case_images: Left popliteal artery aneurysm sac dissected with control of proximal and distal blood flow.

case_images: This examination showed that the graft, the distal LPA, and its terminal branches, the anterior tibial artery, the posterior tibial artery, and the fibular artery, were all patent (Figure 5).
