The most common presentation of a pseudoaneurysm of the superficial temporal artery is from trauma as a pulsatile cystic lesion in the region of the temple, which tends to enlarge steadily, accompanied by a persistent throbbing headache. Histologically they are dissimilar from true aneurysms as they do not contain all three layers of the arterial wall and 95% of these lesions are traumatic in origin. Diagnosis of the lesion can be made by duplex ultrasound scan, ultrasound and CT, CT scan with contrast and angiography. Treatment of this lesion varies within institutions but most commonly a complete excision is preferred with ligation of the proximal and distal vessels, which provides a better cosmetic result.
颞浅动脉假性动脉瘤最常见的表现是由外伤引起，表现为颞部区域的搏动性囊性病变，往往会持续稳定增大，并伴有持续性搏动性头痛。从组织学上看，它们与真性动脉瘤不同，因为它们不包含动脉壁的所有三层结构，且这些病变95%起源于外伤。该病变的诊断可通过双功超声扫描、超声和CT、增强CT扫描及血管造影来进行。不同机构对该病变的治疗方法各异，但最常用的是进行完整切除，并结扎近端和远端血管，这样能获得更好的美容效果。
