矽肺肺门淋巴结蛋壳样钙化,亦称环形钙化,(以下简称肺门壳样钙化)。国内外屡有报导,给矽肺诊断工作提供了一定的资料。但是就壳样钙化的发病情况,发病规律、X线特征及其合并症各地认识尚不够统一,现就我院先后收治的396例铁路隧道工矽肺病人中65例肺门壳样钙化的X线表现分析如下: 一、一般资料 1.本组65例肺门壳样钙化均系住院病人,占同期住院矽肺患者16.4％。 2.工种:铁路隧道开挖工(风钻工)56例;石工6例(其中3例兼作开挖);开挖兼作洞内电工2例;锑矿开挖兼作翻砂铸造工1例。 3.工龄:接触矽尘时间长者29年(石工)短者2年(隧道开挖工),平均接尘时间为4.01年。 4.年龄:本组病例年龄最大者65岁,最小者38岁,50岁以下者52例,占本组病例的80％。详细分布见表1。
Silicosis hilar lymph node egg-like calcification, also known as annular calcification, (hereinafter referred to hilar hull calcification). Repeated reports at home and abroad, to the silicosis diagnosis provides some information. However, the incidence of shell-like calcification, the incidence of disease, X-ray features and complications around the understanding is not enough unity, is now admitted to our hospital in 396 cases of tunnel patients with silicosis in 65 cases of hilar hull calcification X-ray Performance analysis is as follows: First, the general information 1. This group of 65 cases of hilar calcification are hospitalized patients, accounting for 16.4% of patients with silicosis over the same period. 2.Trade: 56 tunnel excavators (wind drill workers); 6 masonry workers (3 of which are also used for excavation); 2 diggers also serve as underground electricians; and 1 case of antimony ore excavation also serves as sand casting and casting workers. 3. Length of service: exposure to silica dust elderly 29 years (masonry) short two years (tunnel excavation workers), the average dust collection time of 4.01 years. Age: The oldest patients in this group were 65 years old, the youngest 38 years old, 52 cases under 50 years old, accounting for 80% of the patients in this group. Detailed distribution in Table 1.
