All available chest radiographs of 50 patients with progressive scleroderma have been freshly evaluated. In 28 cases (56%), pulmonary involvement was diagnosed; its type and severity was classified according to the specimen films of the ILO-U/C 1971 classification for pneumoconiosis. Serial observations in 27 patients spanning a period of one to 21 years have shown that the course of the disease in the lung is unpredictable. Rapid progress of fibrosis is, however, uncommon. Two radiological appearances in the thorax, which are not specific, but are found predominantly in scleroderma are: 1 an air oesophagram on the lateral thorax film (8 cases) and erosions of the upper rib margins (5 cases). The importance of radiological examination lies in the fact that it confirms the clinical diagnosis and that it may indicate the cause of an otherwise undiagnosed pulmonary fibrosis.
对50例进行性硬皮病患者的所有现存胸部X光片进行了重新评估。在28例（56%）患者中诊断出肺部受累；根据国际劳工组织（ILO）1971年尘肺病分类标准的样本片对其类型和严重程度进行了分类。对27例患者进行了为期1至21年的系列观察，结果表明肺部疾病的病程不可预测。然而，纤维化快速进展并不常见。胸部有两种放射学表现，虽不具有特异性，但主要见于硬皮病：1. 胸部侧位片上的食管积气影像（8例）和上肋骨边缘侵蚀（5例）。放射学检查的重要性在于它能证实临床诊断，并且可能提示其他未确诊的肺纤维化的病因。
