Superficial temporal artery (STA) pseudoaneurysms are uncommon and usually secondary to trauma, either iatrogenic or trauma due to sharp objects or blunt trauma. STA pseudoaneurysms may be more common than the literature suggests. Pseudoaneurysm of STA may occasionally lead to severe haemorrhage and be associated with a multitude of bothersome symptoms. Clinical examination revelas a pulsatile mass. Though conventional angiography is gold standard for diagnosing pseudoanuerysms, the utrasound and CT angiography are the base line investigations and are as accurate as conventional angiography in diagnosing this condition. We present a case of traumatic pseudoaneurysm diagnosed by ultarsound and confirmed with CT angiograohy.
