We report a patient with three cerebrovascular events involving the posterior circulation, one of which occurred in conjunction with central retinal artery occlusion. The patient had constitutional findings but had a normal cardiac examination, negative echocardiogram, and negative blood cultures. Angiography on two separate occasions revealed left vertebral artery occlusion. Repeat echocardiography 10 months later, at the time of the third stroke, revealed a left atrial mass consistent with myxoma. In patients with repetitive unexplained embolic events in different vascular distributions and constitutional findings suggestive of atrial myxoma, repeat noninvasive studies are indicated even if the initial workup is negative.
我们报告了一名发生三次涉及后循环的脑血管事件的患者，其中一次事件与视网膜中央动脉阻塞同时发生。该患者有全身性表现，但心脏检查正常，超声心动图检查结果为阴性，血培养结果也为阴性。两次独立的血管造影显示左椎动脉闭塞。10个月后，在第三次中风时重复进行超声心动图检查，发现左心房有一个符合黏液瘤的肿块。对于有不同血管分布反复出现不明原因栓塞事件且有提示心房黏液瘤的全身性表现的患者，即使初始检查结果为阴性，也建议重复进行非侵入性检查。
