摘要
目的探讨艾滋病的脑部MRI表现,总结其影像特征。方法对9例临床疑似艾滋病患者经验血予以证实的脑部MRI征象进行回顾性分析。结果9例脑内病变中均为多发、多部位、多种形态并存的"三多"征象,在艾滋病中具有较高的诊断价值,多数病灶位于大脑半球额、顶叶脑灰白质交界区(8例),1例并发脑干病变,占位效应相对较轻,病变大多在T1WI呈等、低信号,T2WI及FLAIR序列呈高信号,增强后大部呈环状强化;7例并发脑萎缩。结论MRI在诊断艾滋病患者脑部病变方面具有较高的诊断价值。
Objective To study the brain MRI of AIDS patients and summarize its image features.Methods The brain MRI of 9 cases of suspected AIDS patients to be confirmed by blood tests was analyzed.Results Brain pathological changes in all 9 cases was multiple,multi-site and multi-form as in AIDS,it has a high value in AIDS diagnosis,most focus of infection were located in the brain gray matter junctional zone of cerebral hemisphere frontal lobe and parietal lobe（8cases）,1 case complicated by brain stem pathological changes,placeholding effect was relatively minor,mostly pathological changes was even or low signal in the T1WI,T2WI and FLAIR sequences showed high signal enhancement and most showed ring-like enhancement,7 cases complicated by cerebral atrophy.Conclusion MRI has a high value in the diagnosis of brain phthological changes in AIDS patients.
