目的细支气管肺泡细胞癌单纯CT平扫有一些征象不容易发现,只有配合高分辨率HRCT扫描才可发现,所以遇到肺部弥漫性病变、间质性病变或一些结节性病变必须行CT平扫加HRCT扫描。方法先行全肺CT平扫,然后在病变部分再行HRCT扫描。结果细支气管肺泡癌经CT平扫加HRCT扫描可发现磨砂玻璃样密度增高区或肺实变区,以及多发大小不一结节影和其内气泡样透亮影,另外还常可见支气管气相,相邻胸膜凹陷征等。结论细支气管肺泡细胞癌CT平扫可发现肺实变影,两肺弥漫分布的斑片状影,而HRCT扫描不但可以发现以上征象而且还能清晰地发现蜂房征、支气管充气征、磨玻璃影以及肺内散在结节状影。
Purpose Simple bronchial alveolar cell carcinoma simple CT plain scan some signs not easy to find, only with high resolution HRCT scan can be found, so encounter diffuse lung disease, interstitial lesions or some nodular lesions CT Sweep plus HRCT scan. Methods First-line CT scan of the lungs, and then in the lesion part of the HRCT scan. Results of bronchial alveolar carcinoma of the CT scan and HRCT scan can be found in frosted glass-like areas of increased density or pulmonary consolidation, and multiple sizes of nodules and its inside the bubble-like translucent shadow, the other often also visible bronchial vapor phase Adjacent pleural depression signs. Conclusions CT scan of bronchioloalveolar cell carcinoma can be found in the shadow of lung consolidation, diffuse distribution of patchy lung shadow, and HRCT scan can not only find the above signs but also clearly found the aphid, bronchial inflatable sign, ground glass And scattered in the lung nodular shadow.
