以往,用病理学方法,曾在矽肺腹腔淋巴结中发现典型矽结节。此次,择矽肺肺门蛋壳样钙化明显进展的41例,进行X线腹部摄影,发现三例腹腔淋巴结呈不同程度的蛋壳样钙化。但作为一种独立的矽肺钙化类型,其发生和分布范围,钙化形态,均具有一些特点。对这种钙化,利用X线进行无创伤性观察,不需取材作病理检查,也是观察矽肺病灶肺外分布和矽尘的肺外转移的手段。因此,是方便,可行的。本文对矽尘向肺外输送途径提出了看法。
In the past, with pathological methods, have found typical silicone nodules in the peritoneal lymph node of silicosis. The selection of silicosis of hilus eggshell-like calcification in 41 cases of significant progress in X-ray photography and found that three cases of abdominal lymph nodes were varying degrees of egg shell-like calcification. However, as an independent type of silicosis, its occurrence and distribution range, calcification morphology, have some characteristics. This calcification, the use of X-ray non-invasive observation, without taking the material for pathological examination, but also to observe the pulmonary distribution of silicosis lesions and means of extrapulmonary lung metastases. Therefore, it is convenient and feasible. In this paper, we put forward the opinion that silica dust should be transported outside the lungs.
