肺部孤立小结节47例临床分析

Clinical analysis of 47 cases with solitary pulmonary nodules

目的分析47例肺部孤立小结节的临床表现和胸部CT特点判断肺部孤立小结节的良恶性。方法回顾分析我院治疗的47例肺部孤立小结节患者。结果 47例患者中恶性肿瘤28例(59.7%),良性肿瘤12例(25.5%),结核瘤7例(14.9%)。无症状和仅有咳嗽咳痰症状者31例(65.9%)。胸部CT影像中恶性肿瘤结节多边界不清,密度不均、有毛刺、分叶、胸膜皱缩。良性肿瘤结节边界清,密度均匀。结核钙化比率比较高。结论加强肺癌高危人群的普查、监测是发现早期肺癌的途径,结合临床表现和胸部CT特点,是鉴别诊断的最好方法。

Objective To analyze the clinical manifestation and chest CT scan of 47 cases with solitary pulmonary nodules.Methods 47 patients admitted with pulmonary solitary nodules were collected and analyzed.Results Among 47 patients,there were 28 cases with lung cancer（59.7%）,12 cases with benign tumor（25.5%）,7 cases with tuberculosis（14.9%）,31（65.9%）patients were found without symptoms or associated only with cough and sputum.Irregular margins,unsmooth density,speculated margin,lobulated contour and pleural shrinkage in chest CT film were more associated with lung cancer,well-defined margin,smooth were associated with benign tumor.And calcification was more suggestive of tuberculosis.Conclusion Screening of high risk group are useful in finding early lung cancer patients,through clinical manifestation and characteristics in chest CT film are the most effective method for the diagnosis of SPN.
