Selective angiography revealed a pseudoaneurysm arising from the popliteal artery [Figure 1].
CT scan of the distal thigh shows a large mass compatible with the exact size of the aneurysm. The mass has two different compartments: An isointense mass at the periphery filled with old clot encompassing a hyperdense area which is the patent part of the aneurysm.

Contrast-enhanced computed tomography further confirmed a large pseudoaneurysm containing a round, isointense mass (i.e., an intraaneurysmal organized thrombus surrounding/ encompassing a hyperdense area; the patent portion of the popliteal aneurysm) [Figure 2].
The surgical scene after excision of the aneurysm and restoration of the continuity of the arterial blood flow, note that discoloration of the peroneal, sural, and tibial nerves has remained even after neurolysis.

Subsequently, neurolysis of the proximal parts of the peroneal and tibial nerves was performed [Figure 3].
