目的探讨小肺癌CT表现方法对34例经病理证实的小肺癌(首次检查≤2.0cm)行HRCT追踪扫描并回顾性分析CT表现男19例,女15例,年龄38～82岁结果腺癌25例,肺泡癌5例,鳞癌4例;混合磨玻璃密度11例,实性23例结节分叶征25例,毛刺征27例,胸膜凹陷征20例,血管集束征20例,空泡征7例,支气管气相4例7例出现淋巴结转移,8例出现骨或脑转移13例复查1次以上,2例出现密度或大小改变,其中1例实性7年内由0.7cm增大至2.8cm结论肺癌以腺癌最多,部分小肺癌生长缓慢HRCT可以提高显示小肺癌的CT征象
Objective To investigate the CT findings of small lung cancer in 34 cases of pathologically confirmed small lung cancer (initial examination ≤ 2.0cm) HRCT follow-up scan and retrospectively analyzed CT findings of male 19 cases, 15 females, aged 38 to 82 years of age results of adenocarcinoma 25 5 cases of alveolar carcinoma and 4 cases of squamous cell carcinoma. The density of mixed ground glass was 11 cases, the solidity was 23 cases, 25 cases of tuberous follicular sign, 27 cases of burr sign, 20 cases of pleural indentation, 20 cases of vascular bundling sign, Seven cases were retrospectively studied. Lymph node metastasis was found in 7 cases in 4 cases with bronchial gas phase and in 13 cases with bone or brain metastasis in 8 cases. The density or size was changed in 2 cases, of which 1 case was increased from 0.7cm to 2.8 in 7 years cm Conclusion Lung cancer with the most adenocarcinoma, some small lung cancer growth slow HRCT can improve the CT signs of small lung cancer
