Balloon-like Mobile Plaque in the Innominate Artery: Ultrasonographic and Pathological Perspectives of Repetitive Embolism

Mobile plaque in the innominate artery is extremely rare and difficult to diagnose, especially in its acute stage. Its diagnosis is often delayed in many cases, resulting in delayed treatment and poor prognosis. Herein, we report the case of a 69-year-old patient with multiple cerebral infarction only in the right internal carotid artery and vertebrobasilar territories. No embolic sources were found until arterial ultrasonography detected a large balloon-like mobile plaque in the IA. Mobile plaque consisted of high-and low-echoic components and showed balloon-like plaque.
