Atrial septal aneurysm is an uncommon occult cardiac source of cerebral embolism. It is usually asymptomatic, and clinical cardiologic examination and electrocardiography fail to reveal its presence. We report a case of a 34-year-old woman with sudden right hemiplegia and aphasia from occlusion of the left carotid siphon in whom an atrial septal aneurysm was detected by two-dimensional echocardiography. The absence of atherosclerotic risk factors and vascular lesions proximal to the carotid occlusion strengthened a causal relation between atrial septal aneurysm and cerebral infarction. Consequently, two-dimensional echocardiography may be advisable in every patient with unexplained ischemic stroke to detect possible occult embolic cardiac abnormalities.
房间隔瘤是一种罕见的隐匿性脑栓塞心脏来源。它通常无症状，临床心脏检查和心电图无法发现其存在。我们报告一例34岁女性，因左颈动脉虹吸段闭塞突然出现右侧偏瘫和失语，经二维超声心动图检测发现房间隔瘤。颈动脉闭塞近端不存在动脉粥样硬化危险因素和血管病变，这加强了房间隔瘤与脑梗死之间的因果关系。因此，对于每一位不明原因缺血性卒中患者，建议进行二维超声心动图检查，以检测可能隐匿的心脏栓子异常。
