Traumatic Superficial Temporal Artery Pseudoaneurysm Treated With Thrombin Injection

Pseudoaneurysms of the superficial temporal artery are rare. They commonly occur after blunt trauma to the frontotemporal region of the head. There have been less than 400 cases of superficial temporal artery pseudoaneurysms reported. We present a case of a patient referred for a pulsatile head mass. Physical examination and color Doppler ultrasound confirmed the diagnosis of a superficial temporal artery pseudoaneurysm (STA PSA). This was treated with ultrasound guided thrombin injection with complete resolution. Anatomical distribution, diagnosis, and treatment of STA PSA are discussed.
