An 86-year-old man presented with a pulsatile mass in the anterior compartment of the right lower leg. He had become aware of it two months earlier. Computed tomography angiography revealed a fusiform 3.2×5 cm aneurysm of the anterior tibial artery. Mural thrombosis in the aneurysm was absent. Peripheral pulse was normal. We performed aneurysmectomy and revascularization using a saphenous vein graft. Histological findings revealed that the mass was a true aneurysm. The clinical course was good, and the graft has remained patent for six months.
