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。
Objective: To understand the characteristics of Legionnaire bacteriosis (LD) X-ray and CT in combination with clinical manifestations. Methods: Twelve cases of clinically confirmed Legionnaires’ disease were analyzed by X-ray and CT. At the same time, chest X-ray findings of clinical symptoms disappeared. Results: All the 12 cases had lung image changes, 6 cases with pleural changes and 2 cases with mixed infectious lung abscess. Another 2 cases with invasive tuberculosis. Conclusion: Cell isolation and immunofluorescence detection are the basis for diagnosis of Legionnaires’ disease. The diversification of the lungs combined with pleural effusion combined with typical clinical symptoms provide some help for the early diagnosis of Legionnaire bacteriosis. The absorption of the lung lesion lags behind The disappearance of clinical symptoms is another feature of the disease.
