为探讨军团菌病（ＬＤ）肺部Ｘ线、ＣＴ表现特点，回顾性研究了１９９３年１月至１９９６年４月军团菌病肺部影像学等资料齐全的连续性病例，共８１例。其中胸部Ｘ线６０例，胸部Ｘ线＋ＣＴ２１例。所有病例均符合军团菌病诊断标准。本组军团菌病肺部影像学表现出以下特点：①多样性；②胸水多见（２６／８１，３２％）；③游走性（１２／８１，１５％）；④周边分布（２４／８１，３０％）；⑤临床症状影像变化分离（１４／８１，１７％）；⑥病变吸收慢。本病影像学表现缺少特异性，但有一定特点。军团菌病肺部影像学以上特点，对于本病的诊治有实用价值。
To investigate the characteristics of pulmonary X-ray and CT of Legionnaires ’disease (LD), 81 consecutive cases with complete data on pulmonary imaging of Legionnaires’ disease from January 1993 to April 1996 were retrospectively studied. Including chest X-ray 60 cases, chest X-ray + CT21 cases. All cases were in line with the diagnostic criteria of Legionella. This group of Legionnaires lung imaging showed the following characteristics: ① diversity; ② pleural effusion more common (26/81, 32%); ③ walking (12/81, 15%); ④ peripheral distribution (24 / 81,30%); ⑤ clinical symptoms and signs of image changes (14 / 81,17%); ⑥ slow absorption of lesions. Imaging of the disease lack of specificity, but there are certain characteristics. Legionella lung imaging above characteristics, for the diagnosis and treatment of the disease have practical value.
