The lesion was found to be an aneurysm of the superficial temporal artery by using duplex ultrasound (Fig. 1) and a contrast enhanced spiral CT scan of the head (Fig. 2).
The aneurysm was removed by revision surgery of the upper parotid region. a Location of aneurysm (circle) and intended incision (line) have been marked. b Operative view before mobilization. c Higher magnification of operative view before removal of the aneurysm with the draining vessel being lifted

The aneurysm was then excised to prevent any further discomfort (Fig. 3).
a On the cut surface, the resected specimen showed an aneurysmatic dilation (asterisk) of the superficial temporal artery (arrow) which was almost completely filled-out with thrombotic material. b, c On microscopic examination, the thrombus was attached to the intima (asterisk) and comprised layered erythrocytes and fibrin, leaving only a small lumen (hematoxylin-eosin, x20, x40)
