皮质下动脉硬化性脑病的临床和CT表现分析

Clinical and CT findings of subcortical arteriosclerotic encephalopathy

目的探讨皮质下动脉硬化性脑病(SAE)的临床和CT表现,提高对本病的诊断水平。方法回顾性分析78例SAE患者的临床和CT资料。结果SAE早期表现为头晕、头痛、肢体麻木等非特异性症状。当病变发展到一定程度,临床上可表现为渐进性智能障碍,78例中痴呆患者仅8例,表明痴呆并非诊断SAE的必备条件。本病还常伴有脑卒中样表现。CT表现根据Goto等分型分为Ⅰ型43例,Ⅱ型25例,Ⅲ型10例。结论结合临床资料和CT对SAE能明确诊断,特别能早期发现,对本病的早期诊治有重要意义。

Objective To explore the clinical and CT findings of subcortical arteriosclerotic eneephalopathy （ SAE ） , and to obtain a better understanding of SAE, Methods The clinical and CT data of 78 cases of SAE were analyzed. Results The early clinical manifestations of SAE were dizziness, headache, limbs numbing and so on. When the pathological changes developed to certain point,progressive mental retardation might appear. In this study, 8 cases presented with dementia, indicating development of dementia did not necessarily lead to the diagnosis of SAE. But apoplectiform stroke might also appear. According to Goto＇s scale of CT findings,the patients could be divided into type Ⅰ （43 cases） ,type Ⅱ （25 cases） , and type Ⅲ （ 10 cases）. Conclusions CT examination can help the diagnosis of SAE precisely combined with other clinical data, and CT examination plays an important role in the early diagnosis and treatment of SAE.
