While cardiac tumours are rare to begin with, most cardiac tumours are found to be secondary metastases and only a minority of cases are primary tumours. The most common primary cardiac tumours are myxomas. One of the rare causes of cardioembolic strokes is myxomas. A transthoracic echocardiography is an important diagnostic tool often done to exclude cardioembolic causes of stroke. The definitive treatment for cardiac myxoma is surgical resection. The majority of the myxoma-causing strokes involve the middle cerebral artery territory. We present a case of a patient with symptoms of posterior circulation stroke who had right-sided pontine and cerebellar infarct secondary to a left atrial myxoma. She had a successful surgical resection. This is a case report and a literature review on cardiac myxomas causing posterior circulation stroke.
虽然心脏肿瘤本身很少见，但大多数心脏肿瘤被发现是继发性转移瘤，只有少数病例是原发性肿瘤。最常见的原发性心脏肿瘤是黏液瘤。黏液瘤是心源性栓塞性中风的罕见病因之一。经胸超声心动图是一种重要的诊断工具，常用于排除中风的心源性栓塞病因。心脏黏液瘤的确定性治疗方法是手术切除。大多数由黏液瘤引起的中风累及大脑中动脉区域。我们报告一例有后循环中风症状的患者，该患者因左心房黏液瘤继发右侧脑桥和小脑梗死。她接受了成功的手术切除。这是一篇关于导致后循环中风的心脏黏液瘤的病例报告和文献综述。
