摘　　要：目的:分析电焊工尘肺CT表现,提高对电焊工尘肺的诊断水平。方法:回顾性分析2015年1月-2020年12月按职业病诊断标准诊断为Ⅰ期及Ⅱ期的电焊工尘肺患者共103例。对其临床资料及影像特征进行总结分析。结果:本组电焊工尘肺CT表现为小叶中心磨玻璃密度微小结节影44例,小叶分支线状影63例,其中小叶分支线状影合并小叶中心磨玻璃密度微小结节影共20例;腺泡磨玻璃结节影7例,弥漫性磨玻璃改变10例,致密微小结节影6例,伴有肺间质纤维化6例、纤维灶10例、肺结核6例、肺气肿15例、肺大泡14例、支气管扩张1例、淋巴结肿大9例、胸膜增厚19例。结论:电焊工尘肺的CT具有特征性的影像表现,小叶中心磨玻璃密度微小结节影及小叶分支线状影为其特征的CT表现,结合职业病史,可做出明确诊断。Objective:To analyze the CT manifestations of welders'pneumoconiosis and improve the diagnosis level of welders'pneumoconiosis in daily work.Methods:A total of 103 welders'pneumoconiosis patients diagnosed as stageⅠand stageⅡaccording to the diagnostic criteria of menstrual occupational diseases from January 2015 to December 2020 were retrospectively analyzed.The clinical data and image characteristics were summarized and analyzed.Results:The CT findings of welders'pneumoconiosis in this group showed 44 cases of central lobular ground glass micronodules and 63 cases of centrilobular branching linear structure.Among them,20 cases of centrilobular branching linear structure combined with central lobular ground glass micronodules;There are 7 cases of ground glass nodules in acinar,10 cases of diffuse pulmonary ground-glass changes,6 cases of pulmonary dense micronodules.6 cases of pulmonary interstitial fibrosis,10 cases of fibrous foci,6 cases of pulmonary tuberculosis,15 cases of emphysema,14 cases of pulmonary bullae,1 case of bronchiectasis,9 cases of lymph node enlargement,and 19 cases of pleural thickening.Conclusion:The CT features of welders'pneumoconiosis were characteristic.The most characteristic CT findings were the central lobular ground glass micronodules and the centrilobular branching linear structure.Combined with the occupational history,a definite diagnosis can be made.
