A 67-year-old woman presented with a pulsatile mass on the right dorsum of the foot and was diagnosed with a dorsalis pedis artery aneurysm. We performed surgery and confirmed retrograde blood flow distal to the aneurysm intraoperatively. The aneurysm was excised with simple ligation of inflow and outflow vessels. Histopathology showed disruption of the internal elastic lamina and tunica media, consistent with a true aneurysm. True aneurysms of the dorsalis pedis artery are rare, and surgical strategy depends on intraoperative flow assessment and ischemic risk. Our case had a favorable outcome.
