The typical chest computed tomography (CT) finding of the arc welders is ill-defined micronodules diffusely distributed in the lung. We report a rare case of tracheobronchial foreign body in welder without the history of allotriophagy and foreign body aspiration. We used the CT and mineralogical analysis in diagnosis and the flexible fiberoptic bronchoscope in therapy. The CT showed bronchiectasis with pulmonary infiltration of the right lower lobe and high-density shadow in the basal bronchus of the right lower lobe. The foreign bodies were removed by a fibreoptic bronchoscope. Semiquantitative chemical analyses showed that the constituent of foreign body was similar to the dregs which were collected in the same garage. This is an unusual case of the welding-related respiratory diseases, which is different from Welder's siderosis and broncholith.
电弧焊工典型的胸部计算机断层扫描（CT）表现为肺部弥漫性分布的边界不清的微小结节。我们报告一例罕见的气管支气管异物病例，该焊工无异食癖和异物吸入史。我们在诊断中使用了CT和矿物分析，在治疗中使用了可弯曲纤维支气管镜。CT显示右下叶支气管扩张伴肺部浸润，右下叶基底支气管内有高密度影。异物通过纤维支气管镜取出。半定量化学分析表明，异物成分与在同一车库收集的残渣相似。这是一例不寻常的焊接相关呼吸系统疾病病例，与焊工尘肺和支气管结石不同。
