【摘要】 目的探讨艾滋病病毒中枢神经系统感染的影像学特征及诊断。方法对14例确认艾滋病合并中枢神经系统感染患者的CT影像进行分析。结果艾滋病脑炎10例,均无占位效应。脑萎缩现象5例,其中2例单独存在,3例与病灶并存。平扫病变呈片状低密度,以脑白质受累为主;6例累及双侧多个脑叶,分布不对称;2例位于左脑。其中2例增强无强化。巨细胞病毒感染1例,平扫两枕叶见片状低密度,对称分布。弓形体脑病3例,2例见等密度灶并周围水肿,1例显示脑脓肿征象。结论根据CT影像特征,结合流行病学询问,可提出本病疑似诊断。更多还原

【Abstract】 Objective To study imaging diagnosis of HIV complicated brain infection.Methods CT images in 14 cases of AIDSdisease complicated brain infection were analyzed.Results There were 10 cases of AIDS encephalitis,encephalatrophy in 5,of them,2 were alone and 3 with encephalitis.The lesions were low density on CT and mainly involved white matter;6 cases involved in bilateral multiple cerebral lobes,the distribution was dissymmetry;2 cases localized in the left brain.There were no enhancement on contrast-enhanced scan in 2 cases.1 case was cytomegalovirus infection,the lesions were low density in bilateral occipital lobes and symmetry distribute.Toxoplasmosis in 3 cases,of them,2 cases appeared as isointense with surroundings edema,1 appeared as the sign of abscess.Conclusion According to the CT characteristics in combination with the epidemiology,HIV complicated brain infection can put forward to doubt diagnosis更多还原
