Superficial temporal artery aneurysms are rare; when they do occur, they are usually associated with head trauma. Spontaneous true aneurysms of the superficial temporal artery are extremely rare. They are classified as true aneurysms when all three layers of the vessel are found to be involved on histologic examination. Therapeutic options include conservative management, image-guided embolization, and surgical excision. We report a case of an extracranial spontaneous aneurysm of the frontal branch of the superficial temporal artery. A 20-year-old man presented with an asymptomatic, pulsatile, 1-cm forehead mass that had gradually increased in size. The aneurysm was evaluated by clinical examination and three-dimensional computed tomographic angiography. Complete resection was performed with local anesthesia. Histologic examination revealed that the aneurysm involved all three layers of the blood vessel: the tunica intima, tunica media, and tunica adventitia. No atherosclerotic changes or inflammatory cells were found. To the best of our knowledge, this is only the third reported case of a histologically verified spontaneous aneurysm of the frontal branch of the superficial temporal artery. Awareness of this rare pathology in the differential diagnosis of a forehead mass may facilitate diagnosis and prevent complications.
颞浅动脉动脉瘤罕见；一旦发生，通常与头部外伤有关。颞浅动脉自发性真性动脉瘤极为罕见。当在组织学检查中发现血管的三层结构均受累时，它们被归类为真性动脉瘤。治疗选择包括保守治疗、影像引导下栓塞和手术切除。我们报告一例颞浅动脉额支的颅外自发性动脉瘤病例。一名20岁男性患者，前额出现一个无症状、搏动性、1厘米大小的肿块，其大小逐渐增大。通过临床检查和三维计算机断层血管造影对动脉瘤进行了评估。在局部麻醉下进行了完整切除。组织学检查显示，动脉瘤累及血管的三层结构：内膜、中膜和外膜。未发现动脉粥样硬化改变或炎症细胞。据我们所知，这是第三例经组织学证实的颞浅动脉额支自发性动脉瘤报告病例。在鉴别诊断前额肿块时认识到这种罕见的病理情况可能有助于诊断并预防并发症。
