Superficial temporal artery (STA) aneurysms are very rare, and usually occur in young adult men due to blunt trauma as pseudoaneurysms. An 85-year-old male presented with two non-traumatic STA aneurysms. The aneurysms were ligated and resected. Histological examination showed arteriosclerotic fusiform aneurysm. The pathogenesis of non-traumatic aneurysm of the STA appears to be arteriosclerotic change and/or hemodynamic stress.
