摘要
目的 探讨严重急性呼吸综合征 (SARS) ,又称急性传染性非典型肺炎的胸部X线表现特征。方法 52例SARS患者 ,每隔 1～ 3d摄胸部正侧位片 ,而且在 7次以上 ;回顾性分析经临床、流行病学、放射学、实验室检查确诊的 52例SARS患者的胸部X线表现。结果 SARS患者的胸部X线表现为 :3 1例见两肺大片状、小片状密度增高阴影 ;18例见 1侧肺叶或肺段有片状影 ;1例表现为肺段内结节影 ;2例见两肺纹理增粗 ,呈网格状及不规则线状影 ;16例见磨玻璃样影。动态观察并综合分析SARS的X线表现 ,可有如下特征 :三片一间 (病人出现大片状、小片状、斑片状阴影 ,有些病人出现间质性改变 ) ;三多一个不相符 (病灶在两肺中下野多 ;磨玻璃样影多 ;游走性多 ,即上下游走或左右游走 ;症状与X征象不相符 ;一快一慢 (胸部X线表现病灶变化快 ,最终吸收慢 )。结论SARS的胸部X线表现如单独和单次静态观察似乎无明显特征改变 ;但是 ,进行动态观察并综合分析胸部X线征象及变化 。
Objective To investigate the c hest X-ray manifestations in patients with severe acute respiratory syndrome (SARS). Methods Fifty-two SARS patients received chest X-ray examinations at a 1-3 day interval. Reverse transcript polymerase chain reaction (RT-PCR) was used to detect the SARS coronavirus RNA, and specific antibody to SARS coronavirus were detected by enzyme-linked immunosorbant assay (ELISA). Results Out of 52 cases, small patchy or large patchy shadows with intense density in bilateral lung fields were found in 31 cases. The ground-glass opacification was found in 16 cases, small patchy shadows in one lobe or one pulmonary segment were found in 18 cases, the nodular shadow in a pulmonary segment was found in 1 case, and the increased lung-markings in the pulmonary interstitium were found in 2 cases. The follow-up of these SARS patients showed that the rapid changing consolidations in chest X-ray were associated with SARS but not affected by antimicrobial therapy. Conclusion Although there are some specific manifestations in patents with SARS, all patients with SARS symptom should be subjected to chest X-ray examinations continuously at a 1-3 day interval to improve the sensitivity and specificity.
