A rare case of symptomatic true aneurysm of posterior tibial artery

Aneurysms of the infrapopliteal region are uncommon. Of them, true aneurysms are very rare and that of the posterior tibial artery (PTA) are extremely rare. We present a case of a 25-year-old female presented with a pulsatile mass behind the right medial malleolus for 1-year duration. Arterial duplex and angiogram revealed a true saccular aneurysm of the PTA. The aneurysm was resected, and the PTA was reconstructed with a reverse saphenous vein graft.
