The chest radiographs of 24 patients with documented Legionnaires' disease were evaluated. Twenty-two of the 24 patients had positive findings for the disease initially. There was unilateral involvement in 68% and the most common lung shadows were poorly marginated round opacities (46%), diffuse patchy (25%) and peripheral opacities (21%). At peak, 70% of patients had a lobar shadow. Pleural effusions were present in 39% of cases but could be explained by underlying congestive heart failure or renal failure in 7 of the 9. Although the findings are not specific, the radiologist should consider this diagnosis in a patient with compatible clinical history, a pneumonia of obscure etiology, and these radiographic manifestations.
对24例确诊为军团病患者的胸部X光片进行了评估。24例患者中有22例最初有该疾病的阳性表现。68%为单侧受累，最常见的肺部阴影是边界不清的圆形不透明区（46%）、弥漫性斑片状（25%）和周边不透明区（21%）。在高峰期，70%的患者有叶状阴影。39%的病例有胸腔积液，但9例中有7例可由潜在的充血性心力衰竭或肾衰竭解释。尽管这些表现不具有特异性，但对于有相符临床病史、病因不明的肺炎以及这些影像学表现的患者，放射科医生应考虑这一诊断。
