周围型肺癌85例CT征象分析

Analysis of CT signs in 85 cases with peripheral lung cancer

目的分析周围型肺癌的cT征象。方法回顾性分析2012年7月至2017年6月龙游县人民医院经CT检查的85例周围型肺癌患者临床资料，将CT检查征象进行分析并与术后病理诊断确诊结果作对照。结果周围型肺癌患者CT检查结果：病变部位以右上肺后段、双下叶背段、左上肺尖后段、双上叶前段及右下叶后基底段多见，共56例占65．88％。肿块形态球形或近球形占95．29％。肿块大小直径≤50mm58例占68．23％。肿块密度均匀72例，不均匀13例。患者CT征象出现分叶征、毛刺征、棘突征，胸膜凹陷征，支气管血管集中征，空泡征比例分别为：94．12％、88．24％、89．41％、92．94％、52．94％、88．24％。结论周围型肺癌患者CT征象与病例基础分析在周围型肺癌患者的诊断中具有重要意义。

Objective To analyze the CT signs of peripheral lung cancer. Methods From July 2012 to June 2017 ,the clinical data of 85 patients with peripheral lung cancer examined by CT in the People＇s Hospital of Longyou County were retrospectively analyzed. CT findings were analyzed and compared with the results of postoperative pathological diagnosis. Results CT examination showed that the lesions were located in the posterior segment of the right upper lung, the dorsal segment of the double lower lobe, the posterior segment of the left superior pulmonary apex, the anterior segment of the bilateral upper lobe and the posterior basal segment of the right lower lobe in 56 cases, accounted for 65.88%. The shape of the mass was spherical or nearly spherical in 95.29%. The diameter of the mass ≤50mm in 58 cases, accounted for 68.23%. The density of the mass was even in 72 cases, and 13 cases were inhomogeneous. The proportions of lobulation sign,burr sign,spinous process sign,pleural depression sign,bronchovascular concentration sign and vacuole sign were 94.12%, 88.24%, 89.41%, 92.94%, 52.94%, 88.24%, respectively. Conclusion CT findings and ease - based analysis of patients with peripheral lung cancer are of great importance in the diagnosis of patients with peripheral lung cancer,and play a significant role in the clinical efficacy.
