Abstract: Superficial temporal artery pseudoaneurysm a relatively uncommon condition mostly resulted from traumatic injury. Although the most successful standard treatment has been surgical resection, other nonsurgical treatment methods have been employed, including thrombin injection, endovascular embolization, coiling, or conservative treatment. We report a case or right superficial temporal pseudoaneurysm successfully treated with thrombin injection under ultrasound guidance. Our case provides more evidence regarding the efficiency and safety of treatment of pseudoaneurysm with thrombin injection under ultrasound guidance.
Case Presentation: A 41-year-old presented with a progressive right temporal throbbing headache as well as a right preauricular pulsating mass for one week (Figure A). The symptoms started gradually one week after a motor vehicle accident, during which he suffered a large laceration to the right-sided parietotemporal area of the head that necessitated more than 20 stitches. CTA of the head showed right preauricular pseudoaneurysm of the superficial temporal artery of 16 × 9.3 × 8.6 mm in size. Sonography of the right temporal region demonstrated a ”Ying/Yang” flow (Figure B, Video) and some eccentric thrombus within this pseudoaneurysm.
