Chronic interstitial pneumonia, necrobiotic nodules and pleural lesions are felt to be extraarticular manifestations of rheumatoid arthritis (RA). In a prospective study, posteroanterior and lateral chest X-ray films were taken in 89 patients with classical or definite RA (15 male and 74 female), of whom 64 (71.9%) were seropositive. The findings were compared with those of 103 age and sex matched controls. The chest X-rays were blindly evaluated by two of the authors (a pneumologist and a radiologist), and the presence of an interstitial pattern, nodules or pleural lesions was recorded. The following results were obtained: Interstitial pattern, in patients with RA, 5/89 (5.6%), and in controls, 5/103 (4.6%). Pulmonary nodules, in RA, 2/89 (2.2%), and in controls, 2/103 (1.9%). Pleural adhesions, in RA, 32/89 (35.9%), and in controls, 24/103 (23.5%). The results of the present series demonstrate that radiological pulmonary lesions are not more frequent in RA than in controls, similar conclusions having been reached by other authors.
慢性间质性肺炎、坏死性结节和胸膜病变被认为是类风湿关节炎（RA）的关节外表现。在一项前瞻性研究中，对89例典型或确诊的RA患者（15例男性和74例女性）进行了胸部正位和侧位X线片检查，其中64例（71.9%）血清学呈阳性。将结果与103例年龄和性别匹配的对照者进行比较。两位作者（一位肺科医生和一位放射科医生）对胸部X线片进行了盲法评估，并记录了间质模式、结节或胸膜病变的存在情况。获得了以下结果：间质模式，RA患者中为5/89（5.6%），对照者中为5/103（4.6%）。肺结节，RA患者中为2/89（2.2%），对照者中为2/103（1.9%）。胸膜粘连，RA患者中为32/89（35.9%），对照者中为24/103（23.5%）。本系列研究结果表明，RA患者的肺部放射学病变并不比对照者更常见，其他作者也得出了类似的结论。
