Isolated large mobile mass in the thoracic aorta can be due to thrombus or, rarely, aortic tumor. We report the case of a 61-year-old man with no history of medical problems presenting with neurologic deficits and in whom a large mobile echogenic mass in the distal aortic arch was found with transesophageal echocardiography. Given his few cardiovascular risk factors and absence of other systemic symptoms, he received anticoagulant therapy. Subsequent resolution of the aortic mass suggested a diagnosis of thrombus. This case illustrates an unusual manifestation of aortic arch atherosclerosis and underscores the utility of transesophogeal echocardiography for patients with ischemic stroke.
孤立的位于胸主动脉的大型可移动团块可能是血栓所致，也可能是罕见的主动脉肿瘤。我们报告了一例61岁男性患者，该患者无病史，因神经功能缺损就诊，经食管超声心动图检查发现其主动脉弓远端有一个大型可移动的强回声团块。鉴于他的心血管危险因素较少且无其他全身症状，他接受了抗凝治疗。随后主动脉团块消失提示诊断为血栓。该病例说明了主动脉弓动脉粥样硬化的一种不寻常表现，并强调了经食管超声心动图对缺血性卒中患者的实用性。
