摘要(Abstract):
目的探讨儿童烟雾病的临床和影像学特征。方法详细询问患儿病史,进行体检和影像学检查。对儿童烟雾病患者的病因、临床特征、影像学等进行分析总结。结果发病年龄2岁2个月~12岁。6例临床表现为肢体无力或偏瘫,其中3例以此为首发症状;惊厥4例,头痛2例,头晕2例,感觉障碍1例。2例行头颅CT检查者均显示有缺血性改变。6例均行头颅磁共振成像(MRI)检查,4例显示急性脑梗死或小腔隙灶或软化灶,2例无脑实质无异常。6例头颅磁共振血管成像(MRA)检查,均显示颈内动脉虹吸部末端和大脑前或中动脉狭窄或闭塞,脑基底部有异常血管网形成。结论儿童烟雾病多表现为短暂性脑缺血发作(TIA),临床以肢体无力或偏瘫、惊厥为常见症状。MRI联合MRA检查是诊断儿童烟雾病的主要方法之一。
