A man with a pulsatile scalp lesion

“…1,2,3,4 Patients often present 2-6 weeks following the initial injury and may describe an expanding, painless, and pulsatile mass in the temporal region. 1,3 Other associated symptoms may include hemorrhage, dizziness, headache, visual disturbances, facial nerve deficits, or ear pain. 1,3 Clinical suspicion is confirmed via ultrasound or CT angiography.…”

“…Traumatic pseudoaneurysm of the temporal artery is a rare, yet dangerous lesion typically occurring after blunt or penetrating trauma to the temporal region. 1 , 2 , 3 , 4 Pseudoaneurysms occur secondary to disruptions of the arterial wall, resulting in a hematoma enclosed either within the tunica adventitia or surrounding soft tissues, 2 , 3 and are at risk of rupture and hemorrhage. 1 , 2 Due to its anatomic location closeto the skin, the temporal artery is relatively vulnerable to potential traumatic injury.…”
