摘　　要：目的:探讨肺炎型肺癌的MSCT表现特点。方法:结合国内外文献,对我院26例确诊为肺炎型肺癌的影像资料及临床特点进行回顾性分析。结果:病变呈两叶及以上分布17例,其中15例呈叶、段分布,表现为结节和实变影,形似支气管肺炎,2例为弥漫分布,1例为磨玻璃密度,伴有小叶间隔增厚,1例呈粟粒样结节。两叶以下分布9例,其中叶段性分布5例,亚段分布4例,磨玻璃密度4例,混合性磨玻璃密度3例,斑片影2例。26例中出现纵隔及肺门淋巴结肿大6例,支气管充气征7例,血管造影征5例,胸腔少量积液2例。结论:肺炎型肺癌MSCT表现具有一定特点,结合临床具体分析,可提高诊断准确率,确诊仍需病理学检查。Objective To investigate the multislice computed tomography(MSCT)features of pneumonic-type lung cancer.Methods The imaging data and clinical characteristics of 26 confirmed cases of pneumonic-type lung cancer in our hospital were retrospectively analyzed with reference to the relevant literature.Results Seventeen cases had lesions distributed in two or more lung lobes,including 15 cases with lobar and segmental distribution and 2 cases with diffuse distribution.In the 15 cases,the lesions appeared as nodules and consolidation on MSCT,similar to the signs of bronchopneumonia.In the 2 cases,one had ground-glass opacities,with interlobular septal thickening,and the other case had miliary nodules.Nine cases had lesions distributed within a single lung lobe,including 5 cases with segmental distribution and 4 cases with subsegmental distribution.In the 9 cases,4 had ground-glass opacities,3 had mixed ground-glass opacities,and 2 had patchy opacities.Among these 26 cases,6 had mediastinal and hilar lymphadenopathy,7 had an air bronchogram,5 had a CT angiogram sign,and 2 had a small amount of pleural effusion.Conclusion Pneumonic-type lung cancer has certain features on MSCT,which,in combination with clinical analysis,can help improve the diagnostic accuracy.However,a confirmed diagnosis still needs to be based on pathological examination.
