摘　　要：目的 :探讨脑白质稀疏症的发病机理及CT表现与临床症状的关系。方法 :分析 12 4例脑白质稀疏症的CT及临床表现。结果 :脑白质稀疏症的CT可表现为双侧侧脑室枕角周围对称性低密度和 /或双侧侧脑室额角周围低密度、双侧侧脑室周围斑片状对称性低密度或脑白质弥漫性低密度。本病可合并基底节、丘脑腔隙性梗塞及出血。结论 :脑白质稀疏症多发于双侧侧脑室枕角周围 ,也可以发生在双侧侧脑室额角周围 ,在严重病例可累及双侧侧脑室周围部分或全部脑白质区。本病病理表现为双侧侧脑室周围脑白质脱髓鞘 ,脑白质的供血特点、年龄的增长。Objective:To evaluate pathogenesis of Leukoaraosis,relation between CT presentation and clinical symptom in leukoaraosis.Methods:To analyse CT presentation and clinical symptom in the Leukoaraosis of 124 cases.Results:The CT presentation of Leukoaraosis may be symmetrical low density of surrounding occipital horn of bilateral ventricle and/or surrounding frontal horn of bilateral ventricle,symmetrical low density surrounding frontal ventricle or diffused low density of white matter.This disease could be combined with lacunar infarction of basic ganglion,thalamus and hemorrhage.Conclusion:Leukoaraosis often occur in surrounding occipital horn and frontal horn of bilateral ventricle;In serious case,could involved part or all white matter of peri-ventricles.The pathology of the disease is related to demyelination of brain white matter,The blood supplying of the white matter,increase of age,hypertension is the main pathologic process of the demyelination.
