[Non-pulsatile aneurysm of the superficial temporal artery: a report of a case].

Aneurysms of the superficial temporal artery are an uncommon cause for preauricular or parotid masses. Trauma is the most frequent etiology for a pseudoaneurysm and atheromatosis for the true aneurysm. The diagnosis is clinical due to their vascular signs (pulsatile mass, thrill...), these signs care not present when the aneurysmnas thrombosed, being this an unusual event that will make difficult a proper diagnosis. Radiological investigations are needed and helpful under these circumstances. Surgery is curative and recommended, being the excision after proximal and distal ligation of the artery the most accepted procedure. Aneurysms of the superficial temporal artery are rarely reported in the literature. We report a case that showed up as a non-pulsatile preauricular mass to highlight this unusual condition.
