title: Bilateral external carotid artery aneurysms.
abstract: A 60-year-old female was found on a physical examination to have bilateral palpable pulsatile neck masses. She denied local pain, cranial nerve compressive symptoms, or symptoms of cerebral ischemia. Duplex ultrasonography demonstrated bilateral 1.5 x 2.2 cm external carotid artery aneurysms. Isolated bilateral external carotid artery aneurysms were confirmed by computed tomography and angiography. The patient has been treated conservatively, and at 4-year follow-up, she remains asymptomatic, and the carotid artery aneurysms are unchanged in size.
