近纵隔旁肺癌与纵隔肿瘤共45例,其中近纵隔旁肺癌25例,纵隔肿瘤20例,均经手术,病理,痰脱落细胞及纤支镜等证实,故提出以下六个方面X线表现,作为两者对比,分析时参考:①肺血管纹改变。②主动脉弓阴影改变。③患侧膈上升伴膈面幕状阴影改变。④肿块边缘情况。⑥肿块密度和形态改变。⑥气管,食管改变。 There were 45 cases of lung and mediastinal tumors near the mediastinum, including 25 cases of lung cancer adjacent to mediastinal septum and 20 cases of mediastinal tumor. All of them were confirmed by surgery, pathology, hernia exfoliated cells and bronchoscopy, so the following six aspects of X-ray findings were proposed. As a comparison between the two, the analysis refers to: 1 pulmonary vascular striae changes. 2 Aortic arch shadow changes. 3 Ipsilateral ascendant with a change in the shadow of the curtain. 4 Lump edge condition. 6 changes in the density and morphology of the mass. 6 trachea, esophageal changes.
