目的探讨蔺草工尘肺的影像学特点。方法回顾性分析2003年9月至2009年12月确诊为Ⅰ～Ⅲ期蔺草工尘肺14例(Ⅰ期2例、Ⅱ期3例及Ⅲ期9例)的影像学表现。结果 14例中,q影7例,p影6例和r影1例。5例单纯型蔺草工尘肺的总体密集度在1/0～3/+,总体密集度均在上肺区5例,其中右侧4例,左侧1例。9例复杂型蔺草工尘肺的总体密集度为1/1～3/3,上肺区5例、中肺区3例和下肺区1例;其中3例在薄层计算机断层扫描(CT)表现为q影在上肺区和肺的后部分布较多,呈淋巴管周围分布;9例中,大阴影A级1例、B级4例和C级4例;大阴影仅在上肺区5例,从上肺区向中肺区或下肺区延伸各1例,在右上肺区和左中肺区1例,以及在左上和右中肺区1例;大阴影呈对称性分布7例(77.8%),右上肺大阴影对应左肺小阴影聚集2例(22.2%);3例加做CT检查,显示2例大阴影位于后1/3,1例占据中1/3和后1/3;9例中,共出现大阴影17个,右肺10个,平均6.2cm×3.4cm;左肺7个,平均6.0cm×3.1cm。大阴影边缘清楚14个,边缘有长毛刺5个,外缘或长轴与侧胸壁平行7个,空气支气管征5个,斑点状钙化6个,疤痕旁肺气肿9个,邻近有胸膜增厚粘连15个。1例有纵隔淋巴结肿大伴斑点状钙化。结论蔺草工尘肺是一种特殊类型的尘肺,其影像学表现与矽肺有所不同。
Objective To investigate the imaging characteristics of Rush workers’ pneumoconiosis. Methods The clinical manifestations of 14 cases of pneumoconiosis (Grade Ⅰ ~ Ⅲ) from September 2003 to December 2009 were analyzed retrospectively. The imaging findings were 14 cases (Ⅰ stage 2 cases, Ⅱ stage 3 cases and Ⅲ stage 9 cases). Results 14 cases, q-ray in 7 cases, p-ray in 6 cases and r-ray in 1 case. The overall density of 5 simple lush workers’ pneumoconiosis was 1/0 ~ 3 / +, and the overall intensity was 5 in the upper lung area, including 4 on the right and 1 on the left. The overall density of 9 cases was 1/1 ~ 3/3, 5 cases in the upper lung area, 3 in the middle lung area and 1 in the lower lung area. Among them, 3 cases were diagnosed by thin-slice computed tomography ) Showed q shadow in the lung area and rear of lung distribution more, distributed around the lymphatic vessels; 9 cases, 1 case of large shadow A grade, 4 cases of B and 4 cases of C; large shadow only in the upper 5 cases in the lung area, 1 case extended from the upper lung area to the middle or lower lung area, 1 case in the right upper lung area and the left middle lung area, and 1 in the left upper and right middle lung area. The large shadow was symmetrical There were 7 cases (77.8%) in the upper right lung and 2 cases (22.2%) in the left upper lobe and the lower left lobe in the upper right lung, and 3 cases And 1/3; 9 cases, a total of 17 large shadow, right lung 10, an average of 6.2cm × 3.4cm; left lung 7, an average of 6.0cm × 3.1cm. Large shadow edge of the clear 14, the edge of a long burr 5, the outer edge or long axis and chest wall parallel to 7, air bronchial sign 5, 6 spots of calcified, scar emphysema next to 9, adjacent to a pleural augmentation Thick adhesion 15. One case had mediastinal lymph nodes with speckled calcification. Conclusion Rush Pneumoconiosis is a special type of pneumoconiosis whose imaging features are different from that of silicosis.
