摘要
目的评价烟雾病的诊断方法,讨论其鉴别诊断。方法回顾性分析11例烟雾病的CT、M RI及M RA资料,分析脑实质及脑血管的形态学改变。结果C T及M R I表现为脑实质改变:脑出血3例,脑梗死6例,脑萎缩2例;M RA均见有不同程度的颈内动脉分叉以上狭窄或闭塞,其中双侧颈内动脉狭窄6例,单侧颈内动脉狭窄5例;大脑中动脉狭窄20支,大脑前动脉狭窄18支,大脑后动脉狭窄14支;9例同时显示异常血管网。结论烟雾病主要靠放射学诊断,M RA可很好地显示烟雾病异常血管,可作为筛查烟雾病首选方法。诊断时,要排除脑中风、动脉瘤和动静脉畸形出血。
Objective To evaluate the diagnostic methods and manifestations ofmoyamoya disease and discuss its differential diagnosis. Methods The CT, MR1 and MRA data of the 11 cases affirmatively diagnosed as moyamoya disease by DSA were retrospectively analyzed to study the changes of cerebral parenchyma and vessels morphologically. Results CT and MRI displayed the changes of cerebral parenchyma： 3 cases of cerebral hemorrhage, 6 cases of cerebral infarction, 2 cases of local brain atrophy. MRA demonstated different degrees of stenosis or obstruction distal from the internal carotid bifurcation in all cases, including stenosis of bilateral carotid fork （6 cases） and stenosis of lateral carotid fork （5 cases）. Meanwhile, it showed stenosis in 20 middle cerebral arteries, 18 anterior cerebral arteries, 14 posterior cerebral arteries, and abnormal vessel network in brain region （9 cases）. Conclusion Moyamoya disease may be diagnosed mainly by radiology. MRA can display the abnormal vessels from moyamoya disease, and so it can be used as the preliminary method for the diagnosis of myamoya disease. Simple stroke, cavernous angioma and intracranial arterioven malformation should be excluded in case of diagnosis and differential diagnosis.
