The superficial temporal artery (STA), the terminal branch of the external carotid artery, is divided into the frontal (anterior) and parietal (posterior) branches. The frontal branch of the STA is located superficially on the anterior region of the scalp, making it especially susceptible to trauma. Here, we report a traumatic pseudoaneurysm of the STA in a 7-year-old boy who was injured in a minor car accident. A physical examination showed only a small bruise on the patient's forehead, and all vital signs were stable at the emergency room of our medical center. A facial computed tomography scan showed no significant findings. However, the boy later re-visited the hospital with slight swelling on the right forehead, and an ultrasonography scan revealed a hematoma near the right temporal artery. The resected hematoma (approximately 2 cm) was diagnosed as a traumatic pseudoaneurysm. Awareness of the possibility of a traumatic pseudoaneurysm in the STA may prevent a circumspect diagnosis in the future.
颞浅动脉（STA）是颈外动脉的终末分支，分为额支（前支）和顶支（后支）。STA的额支位于头皮前部浅表位置，使其特别容易受到创伤。在此，我们报告一例7岁男孩因轻微车祸受伤导致的STA创伤性假性动脉瘤。体格检查显示患者前额仅有一处小瘀伤，在我们医疗中心的急诊室所有生命体征均稳定。面部计算机断层扫描未发现明显异常。然而，该男孩后来因右前额轻度肿胀再次就诊，超声扫描显示右颞动脉附近有血肿。切除的血肿（约2厘米）被诊断为创伤性假性动脉瘤。认识到STA发生创伤性假性动脉瘤的可能性，可能有助于未来进行审慎诊断。
