Traumatic superficial temporal artery pseudoaneurysm managed with ultrasound-guided compression

Superficial temporal artery aneurysms are rare, accounting for approximately 1% of all arterial aneurysms, with 95% of these being pseudoaneurysms. They are most commonly caused by trauma to the temporal region. Although ultrasound-guided compression has been described as a management technique, it has been believed to be ineffective. This report describes the case of an 81-year-old female on anticoagulation who presented with a pulsatile mass over her left temporal region 4 weeks after a fall. Arterial ultrasound confirmed the presence of a pseudoaneurysm of the frontal branch of the superficial temporal artery, which was successfully treated with ultrasound-guided compression. This case therefore highlights that ultrasound-guided compression can serve as an effective non-surgical treatment option for pseudoaneurysms of the superficial temporal artery.
