摘要
目的:探讨艾滋病(AIDS)合并卡氏肺囊虫肺炎(PCP)的不同时期的CT表现。方法:将22例临床确诊的AIDS合并PCP患者胸部CT检查不同病理时期的CT表现及治疗后的CT随访进行分析。结果:早期改变较少(占5%);中期较多,影像学改变典型,表现以双肺实质对称性渗出性改变为主的磨玻璃影,预后较好(占82%);晚期表现较复杂,除了肺实质改变外,以间质改变为主的网格状影,弥漫性小结节影或网织结节影,胸膜下"月弓征",肺门和(或)纵隔淋巴结肿大,胸腔积液,小片实变较多见,预后差。结论:胸部CT不仅可以充分显示PCP的病变影像,同时认识不同病理时期的CT表现,做到早期诊断,早期治疗,避免发生成人呼吸窘迫综合征甚至死亡。
Objective：To study manifestations in different stages of AIDS complicating pneumocystis carinii pneumonia（PCP）.Methods：To perform the retrospective analysis on the clinical and radiological data in 22 cases of AIDS complicating Pneumocystis carinii pneumonia,including chest CT scans in different pathological stages and CT follow up after treatment.Results：The early changes were less and undetectable,accounting for 5%;the middle stage had more changes with typical CT images demonstrated by symmetrical exudative ground glass appearance,with better prognosis,which accounting for 82%;the manifestations in the advanced stage were complicated,except lung parenchyma changes,showing main parenchyma changes demonstrated by gridding shadow,diffuse nodule or reticulonodular shadows,subpleural＂moon bow sign＂,swollen lymph nodes in hilus of lung and/or mediastinum,pleural effusion and small pieces of consolidation,with poor prognosis.Conclusion：The chest CT in AIDS patients complicated with Pneumocystis carinii pneumonia not only fully displays the pathological images of PCP,but also cognizes the CT manifestation in different pathological stages to achieve early diagnosis and early treatment for avoiding ARDS and even death happening.
