【摘要】 目的探讨HRCT(High-resolution CT)在诊断肝移植术后巨细胞病毒(CMV)肺炎的临床价值。方法收集11例肝移植术后确诊为CMV肺炎患者的HRCT,由两名放射科医生统计分析病灶的形态及分布特征。结果毛玻璃影10例,多发结节8例,斑片状实变影4例。100%(11/11)患者肺内见到多种形态病灶共同存在:毛玻璃影与多发结节4例,毛玻璃影与实变影3例,实变影与多发结节1例,毛玻璃影、实变影与多发结节三者共同存在3例。100%(11/11)例病变均累及双肺,9例病灶分布于肺内外带,仅分布于外带和内带各3例。病变累及下叶11例,累及中叶与上叶分别为10例、9例。结论肝移植术后患者肺部病变的HRCT表现为双肺混合存在的毛玻璃影、多发结节及斑片实变影时,提示肺内病变为CMV肺炎的可能。更多还原

【Abstract】 Objective To discuss the value of HRCT(High-resolution CT) in the diagnosis of cytomegalovirus pneumonia after liver transplantation.Methods The HRCT appearances of 11 patients with cytomegalovirus pneumonia after liver transplantation were retrospectively analyzed.Results 10 cases of ground-glass opacification,8 cases of multiple nodules and 4 cases of air space consolidation were seen in 11 patients.A combination of ground-glass opacities,nodules,and areas of air-space consolidation were shown in 100%(11/11) patients.4 cases of ground-glass opacity and nodules,3 cases of ground-glass opacity and air-space consolidation,1 case of air-space consolidation and nodules and 3 case of ground-glass opacity,air-space consolidation and nodules were identified.Bilateral abnormalities were seen in all patients.Lesions were distributed in peripheral and internal zones lungs in 9 cases.Lesions only in peripheral zone of lungs and in internal zone of lungs were demonstrated in 3 cases respectively.Lesions in lower lobe,medial lobe and upper lobe were revealed in 11,10 and 9 cases respectively.Conclusion A combination of groundglass opacities,nodules,and areas of air-space consolidation were the most common HRCT appearances of cytomegalovirus pneumonia after liver transplantation and could be the evidences of diagnosis of cytomegalovirus pneumonia.更多还原
