【摘要】 目的：结合临床表现认识军团杆菌病（ＬＤ）Ｘ线和ＣＴ特点。方法：对１２例临床证实的军团杆菌病进行Ｘ线和ＣＴ分析，并同时追访观察了临床症状消失后胸部影像表现。结果：１２例均有肺部影像改变，６例伴有胸膜改变，２例伴混合感染性肺脓肿。另有２例伴发浸润性肺结核。结论：细胞分离和免疫荧光检测是军团杆菌病确诊的依据，肺部改变多样化同时伴有胸水与典型临床症状相结合，对军团杆菌病的早期诊断提供了一定帮助，肺部影像病变吸收滞后于临床症状消失是本病的又一特点。更多还原

【Abstract】 Objective:To realize radiographyic and computed tomography(CT)diagnostic features of legionnaires disease(LD)correlated to clinical manifestations.Methods:Radiographic and CT manifestations of 12 patients with LD proved by the clinic were analysed.At the mean time we also studied the results of follow-up and analysed radiographic and CT manifestationa after clinical symptoms disappeared.Results:There were 12 cases of lungs changes on radiography and CT,6 of them were associated with pleuras changes,2 of them were associated mixed infectious pulmonary empyemas,2 of them were associated with intrusive pulmonary tuberculoses.Conclusion:LD diagnosis relies on the methods of bacteria isolation and immunization fluorescence inspection.It is helpful to diagnose early LD to correlated to lungs′ changes of variety on radiography and CT,pleuras and typical clinical manifestations.Another feature of LD is lung’s abnormal manifestation on radiography and CT disappear behind the disappearance of clinical symptoms.更多还原
