肺门淋巴结环形钙化,在一般胸部疾病中很少见,但在粉尘作业工人中,尤其是从事矽尘作业和矽肺患者中,则屡见不鲜。我组自1963年开展尘肺检查诊断工作以来,共照X线胸片12,964例,发现肺门淋巴结环形钙化者23例,占粉尘作业照片人数的0.18％,现将23例有关资料整理分析如下。一、工种和X线诊断 23例肺门环形钙化患者中,风砧工9例:计Ⅰ期合并肺结核2例,Ⅱ期和Ⅱ期合并肺
Hilar lymph node ring calcification, rare in the general chest disease, but dust workers, especially those engaged in silica dust operations and silicosis, are not uncommon. Since 1963 pneumoconiosis diagnosis and diagnosis work has been carried out in our group, a total of 12,964 cases of X-ray chest radiographs were found. Twenty-three cases of ring-shaped calcification of hilar lymph nodes were found, accounting for 0.18% of the number of photographs of dusty operations. The data of 23 cases were analyzed as follows. First, the type of work and X-ray diagnosis 23 cases of hilar ring calcification in patients with wind anvil work in 9 cases: the first stage with tuberculosis in 2 cases, Ⅱ and Ⅱ with lung
