Emboli from left atrial myxomas are a recognized cause of cerebral ischaemia. The myxomatous embolus may infiltrate the cerebral arterial wall, resulting in aneurysmal dilatation with a risk of rupture. Myxoma-associated cerebral haemorrhage has been described in patients with progressive neurological dysfunction. We report a new presentation. Our patient, a previously healthy 20 year old girl, developed acute intracerebral haemorrhage for which craniotomy was performed. Histology of evacuated haematoma revealed an intravascular fragment of myxoma. Echocardiography demonstrated a left atrial myxoma which later was uneventfully excised. Early diagnosis of embolic cardiac myxoma requires awareness of the diversity of clinical manifestations, and careful histological analysis of surgical specimens.
左心房黏液瘤的栓子是脑缺血的一个公认病因。黏液瘤栓子可能浸润脑动脉壁，导致动脉瘤样扩张并有破裂风险。黏液瘤相关的脑出血在有进行性神经功能障碍的患者中已有描述。我们报告一种新的表现形式。我们的患者是一名此前健康的20岁女孩，发生急性脑出血并接受了开颅手术。清除的血肿组织学检查显示为黏液瘤的血管内碎片。超声心动图显示左心房黏液瘤，随后顺利切除。栓塞性心脏黏液瘤的早期诊断需要认识到临床表现的多样性，并对手术标本进行仔细的组织学分析。
