Pulmonary siderosis is one kind of pneumoconiosis caused by the long term inhalation of iron dust. It occurs in a number of occupations including steel rolling and grinding, welding, polishing, casting, boiler scaling, iron ore mining and emery working. Here we report a case of pulmonary siderosis. A 49-year-old male who had worked in an iron foundry for 30 years was admitted because diffuse micronodular lesions were seen in both lung fields on a routine chest radiographic study. A pulmonary function test disclosed a mildly restrictive ventilatory defect. Transbronchial lung biopsy revealed a significant amount of iron dust deposited within a fibrous nodule by which confirmed the diagnosis of pulmonary siderosis.
肺铁末沉着症是一种因长期吸入铁尘引起的尘肺病。它发生于许多职业，包括轧钢、研磨、焊接、抛光、铸造、锅炉除垢、铁矿石开采和金刚砂加工。在此我们报告一例肺铁末沉着症病例。一名49岁男性，在铸铁厂工作30年，因常规胸部X线检查发现双肺野有弥漫性小结节病变而入院。肺功能测试显示有轻度限制性通气功能障碍。经支气管肺活检显示在一个纤维结节内有大量铁尘沉积，由此确诊为肺铁末沉着症。
