    AbstractTraditionally, patients with symptomatic external carotid stenosis present with neck or face pain, retinal ischemic symptoms or jaw claudication and rarely as ipsilateral cerebrovascular events. In this present case, our patient suffered a stroke from a paradoxical embolism from the external carotid, without involvement of the internal carotid artery. A plaque ulceration of the external carotid's origin was the cause of this cerebral emboli. Duplex ultrasound showed a pathologic left external carotid, with a floating thrombus in the internal carotid. The diagnostic was confirmed by a computerized tomography scan. An external carotid thromboendarterectomy was performed 6 days after symptom onset, and intraoperative findings confirmed the plaque rupture with an extensive clot in the carotid bifurcation.
