艾滋病合并脑血管疾病的影像学基础研究

目的为AIDS合并脑血管疾病提供影像学诊断基础。方法对25例AIDS合并脑血管病人行影像学检查，组织活检，并对2例AIDS尸体进行断层解剖。结果13例脑梗塞MRI显示点状，片状长T1长T2信号；4例脑萎缩MIni显示两侧大脑总质量减少，脑沟增宽，增深，侧裂池扩大，8侧脑血管狭窄MRA显示脑血管迂曲、狭窄。病检显示为脑动脉病毒性肉芽肿性炎、病毒性脑炎。结论影像学检查可以成为艾滋病合并脑血管病的诊断分类与治疗预后的依据。

Basic Study on Imaging of combined Cerebrovascular diseases in AIDS

Objective To provide imaging diagnostic basis of combined cerebrovascular diseases in AIDS. Methods 25 AIDS cases with combined cerebrovascular diseases were performed by imaging studies and sectioned biopsy, and two cases by AIDS--sectional anatomy of the body. Results 13 cases with cerebral infarction exhibited points or flakes in long TI or long T2 signals with MRI; four cases of brain atrophy with MRI showed decreased bilateral brain mass, the brain widened Ditch, deepening and expanding sylvian cistern; 8 cases of cerebral vascular stenosis, being tortuous and narrow in brain blood vessels with MRA.Pathologic examination revealed granulomatous inflammation of the cerebral arteries virus and viral encephalitis. Conclusion Imaging examinations can constitute the basis for the diagnostic~ classification and treating prognosis of the combined cerebrovascular diseases in AIDS.
