在相对年轻的妇女中,为什么当接触重金属碳化物烟尘后,会发展成急性进行性呼吸衰竭,引起了作者对重金属尘肺的回顾。在许多与职业有关的肺部疾病中,在x线学上尚未发现特征性的改变。作者希望通过对本病的研究,从x线形态与临床表现方面得到一些认识,以便及早作出诊断。作者报告三例从事钨碳化物研磨女工患重金属尘肺,表现为肺内广泛的弥漫性纤维化。她们的平均年龄为35岁,最年轻者只有22岁,年长者52岁。重金属碳化物烟尘接触史平均5年8个月,最短者5年,最长 Why relatively young women, when exposed to heavy metal carbide fumes, can develop acute progressive respiratory failure has aroused the author’s review of heavy metal pneumoconiosis. In many occupational-related lung diseases, no characteristic changes have been found in x-ray studies. The authors hope that through the study of this disease, some knowledge about the x-ray appearance and clinical manifestation may be obtained so as to make an early diagnosis. The authors report three cases of women workers suffering from tungsten carbide grinding heavy metal pneumoconiosis, the performance of a wide range of diffuse pulmonary fibrosis. Their average age is 35, with the youngest being 22 and the elder 52. The average history of exposure to heavy metal carbides and fumes is 5 years and 8 months, the shortest is 5 years and the longest
