title: [Case of an idiopathic dissecting aneurysm of the superficial temporal artery: a case report].
abstract: Aneurysms of the superficial temporal artery are usually traumatic in origin an are pseudoaneurysms. We present a rare case of an idiopathic dissecting aneurysm of the superficial temporal artery in a 40-year-old man without history of trauma. The patient had a pulsatile mass in the left temporal region. Angiography showed a fusiform dilatation at the left superficial temporal artery and both the true lumen and the false lumen were recognized. Resection of the aneurysm was performed. Postoperatively, the patients complaints disappeared completely. Histopathological examination of the specimen revealed a dissecting aneurysm. We investigated the histological findings by comparing them to angiographical findings.
