目的:认识艾滋病的脑部与胸部的CT和MRI影像学表现,并评价其诊断价值。材料和方法:对临床确诊的4例男性艾滋病患者CT表现进行分析,2例脑CT,1例胸CT。结果:3例脑CT表现为脑白质的多发性、对称性脱髓鞘改变。1例胸CT表现为左上、右下肺内大片炎性、渗出性病灶合并有不规则空洞,临床确诊为放线菌感染。结论:艾滋病的影像学表现无论在中枢神经系统和胸部均无特异征象,需密切结合临床资料方能提出符合性或提示性诊断意见。影像学检查可了解艾滋病的受累部位和程度,为治疗及预后评价提供重要信息,这一点在中枢神经系统尤为重要。
Objective: To understand the CT and MRI features of brain and chest in AIDS and to evaluate its diagnostic value. Materials and Methods: The clinical manifestations of 4 cases of HIV-positive patients were analyzed, 2 cases of CT and 1 case of CT. Results: Three cases of brain CT showed multiple, symmetrical demyelination of white matter. One case of thoracic CT showed the upper left and right lower lung large inflammatory, exudative lesions with irregular cavities, clinically diagnosed as actinomycetes infection. Conclusion: The imaging manifestations of AIDS have no specific signs both in the central nervous system and in the thorax. It is necessary to combine the clinical data closely to provide the conformable or suggestive diagnosis. Imaging examination can understand the location and extent of AIDS, providing important information for the treatment and prognosis evaluation, which is particularly important in the central nervous system.
