To clarify whether there were any differences in MR appearance between the childhood and the adult moyamoya syndromes.
We compared the cranial MR findings in four children under the age of 6 who had moyamoya syndrome with previously documented adult cases.
Moyamoya syndrome in younger children exhibited a significant increase in cortical and subcortical infarction, and a decreased incidence of deep white matter infarction in the centrum semiovale and basal ganglia, in contrast to adult cases. There were no remarkable differences between these two groups of moyamoya cases with regard to the occlusive changes of the internal carotid and middle cerebral arteries, or to the flow void sign on MR.
These differences in the sites and frequencies of infarctions between the childhood and the adult moyamoya syndromes observed on MR might reflect differences in the cerebral circulation.
明确儿童烟雾病综合征与成人烟雾病综合征在磁共振成像（MR）表现上是否存在差异。
我们将6岁以下4例患有烟雾病综合征的儿童的头颅MR检查结果与先前记录的成人病例进行了比较。
与成人病例相比，年幼儿童烟雾病综合征的皮质和皮质下梗死显著增加，半卵圆中心和基底节深部白质梗死的发生率降低。这两组烟雾病病例在内颈动脉和大脑中动脉的闭塞性改变或MR上的流空信号方面没有显著差异。
在MR上观察到的儿童和成人烟雾病综合征梗死部位和频率的这些差异可能反映了脑循环的差异。
