本文介绍了18例钙化型矽肺的发病情况和x线表现,表明:①矽肺组矽肺钙化的发生率(7.5％)高于煤矽肺组(0.66％),两者有非常显著差别(x~2=15°4,P<0.01);以掘进工和坑探工多见。提示矽肺钙化形成与接触游离二氧化矽量高的粉尘有关。②矽肺钙化多见于Ⅱ期和Ⅲ期病例,且多数始现于Ⅱ期和Ⅲ期病程,说明矽肺钙化不宜作为诊断早期矽肺的指标,而只是矽肺病变所致的一种x线征象。③肺门淋巴结蛋壳样钙化显示后,矽肺病变仍可继续发展。
The incidence and x-ray findings of 18 cases of calcified silicosis were described in this paper. The results showed that: (1) the incidence of silicosis (7.5%) in silicosis group was significantly higher than that in coal silicosis group (0.66%) = 15 ° 4, P <0.01). It is more common among diggers and pit explorers. Tip silicosis calcification and exposure to high silica dust free. ② silicosis calcification more common in stage Ⅱ and Ⅲ cases, and most of the disease appeared in stage Ⅱ and Ⅲ, indicating that silicosis calcification should not be used as an indicator of early silicosis, but only caused by a silicosis of x-ray signs. Hilar lymph node egg-like calcification showed that silicosis can continue to develop.
