摘　　要：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。Objective To study the CT findings of small lung cancer. Methods 34 cases of small lung cancers（ ≤2.0 cm on first CT scan） proved by pathology were undergone HRCT and the CT findings were retrospectively analysed. There were 19 males and 15 females, ranged from 38 to 82 in age. Results The histological type included：adenocarcinoma in 25 ,brochioloalveolar carcinoma in 5 and squmocellular carcinoma in 4. The density of lesions appeared as mixed ground glass opacity C GGO） in 11 ,solid density in 23. There were lobulation in 25 cases, speculation in 27 cases,pleural tag in 20, vessel convergence in 20,vacuole sign in 7 ,air brochogram in 4. There were metastasis of the lymph nodes at the pulmonary hilus and the mediastina in 7 ,and the metastasis of the bone or the brain in 8.13 cases underwent repeated CT scan one more times within 2 week to 7 years ,the lesions in 2 cases were changed in density or size, the lesion of one case grew from 0.7 cm to 2.8 cm in maximum diameter in 7 years. Conclusion Adenocarcinoma is the most common type of small lung cancer. The part of small lung cancer might grow very slowly. HRCT can improve the CT signs of small lung cancer.
