脑白质稀疏症临床及CT特点分析(附260例报告)

Analysis About Clinical and CT Characters of Leukoaraiosis (Report of 260 Cases)

目的：探讨脑白质稀疏症临床及ＣＴ特点，以提高对脑白质稀疏症的诊断水平。材料与方法：２６０例，男性１６５例，女性９５例，年龄５０～９５岁，平均７６岁。临床症状均有头晕、恶心及偏瘫、肢麻、失语、认识障碍或痴呆等神经症状，结合ＣＴ特点对照分析。结果：本病好发于５０岁以上，并与年龄成正比，临床上常伴高血压、冠心病、动脉硬化、糖尿病等危险因素；渐进性痴呆和智力减退是常见表现；多伴发急性或亚急性卒中，出现感觉、语言及运动障碍。ＣＴ特征表现为双侧脑白质对称性低密度灶，或并发脑梗塞、脑出血及脑萎缩。结论：熟悉本病的临床和ＣＴ特点，对提高本病的ＣＴ诊断正确率有重要价值。

Purpose: To explore clinical and CT characters of leukoaraiosis (LA) in order to improve diagnostic level of LA. Materials and Methods: 260 LA cases (male 165, female 95, mean age 76 years old) were examined. Its clinical features included mental dysfunction or dementia. CT features were combined for analysis. Results: LA were more often above 50 years old, its occurrence was correlative with ages. It could be accompanied by hypertension, coronary cardiac disease, arteriosclerosis, diabets. Its common clinical features included gradual dementia and mental degeneration. Acute of subacute stroke, feeling, motor, language dysfunction were found. Its CT features included bilateral symmetric white matter hypo - density. It could be accompanied by cerebral infarction, hemorrhage and atrophy. Conclusion: To understand clinical and CT characters of LA is important for improving CT diagnostic level of LA.
