动脉硬化性脑白质病的CT表现与临床分析

The CT manifestations and clinical analysis of cerebral white matter disease due to arterial sclerosis

目的 :探讨动脉硬化性脑白质病的临床与CT表现特点。方法 :收集 10 0例动脉硬化性脑白质病的临床与CT资料进行综合分析。结果 :10 0例的CT表现为 :弥漫性脑白质低密度改变 ,主要分布在双侧脑室旁及半卵圆中心白质区 ,病灶多呈条带状及月晕状。合并脑萎缩 90例 ;脑梗塞 76例 ,其中 2 5例有大的梗塞灶 ,其余为腔隙性梗塞 ;脑出血 9例 ,其中位于壳核 5例 ,丘脑 3例 ,小脑 1例 ;有 15例伴发基底节区软化灶。增强扫描 8例 ,显示病灶无明显增强。结论 :动脉硬化性脑白质病是发生于老年人的缺血性脑血管病 ,高血压动脉硬化是其主要发病因素。

Objective : To explore CT manifestation and clinical analysis of cerebral white matter disease due to arterial sclerosis .Methods: 100 cases cerebral white (substances )disease due to arterial sclerosis were collected and analysed synthetically .Results:100 cases of such disease: diffused low density changes of white cerebral substance mainly distributed by both sides in ventricles of the brain and (white substance area round center of half an ovum .)The focus mostly presented banding or lunar form .Amalgamate encephalatrophy 90 cases;combining cerebral embolism 76 cases and there were 25 cases among them have large area of embolic focus, others have small crack embolism, combining cerebral hemorrhage 9 cases, and there were 5 took place in shell muclear, 3 in thalamus, 1 in cerebellum.15 cases accompanied the basal ganglion area soften focus.8 strenghtening scanuning haven't show obvious amplification focus.Conclusion: Cerebral white substance disease often took place to the old men, it belonged to cerebral vessal disease due to ischemia。Its main pathogenic factor was HBP arterial sclerosis.
