Abstract

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.
