A traumatic pseudoaneurysm of the superficial temporal artery

Pseudoaneurysm arising from the superficial temporal artery (STA) is very rare and is most commonly caused by blunt trauma. Most pseudoaneurysms of the STA usually present as a painless pulsating mass, with concomitant symptoms according to location, and their size may rapidly increase. The treatment of choice is ligation and resection. We present a case of pseudoaneurysm arising from STA after a penetrating injury caused by broken glass. We describe the history, findings of physical examination, Doppler sonography, angiography, histopathology, and the outcome of treatment. We also include a brief review of this condition.
