The incidental finding of a pulmonary nodule on computed tomography (CT) is becoming an increasingly frequent event. The discovery of such a nodule should evoke the possibility of a small bronchogenic carcinoma, for which excision is indicated without delay. However, invasive diagnostic procedures should be avoided in the case of a benign lesion. The objectives of this review article are: (1) to analyze the CT criteria defining benign nodules, nodules of high suspicion of malignancy and indeterminate nodules, (2) to analyze the diagnostic performances and limitations of complementary investigations requested to characterize indeterminate lung nodules, (3) to review the criteria permitting to assess the probability of malignancy of indeterminate nodules and (4) to report on the new guidelines provided by the Fleischner Society for the management of small indeterminate pulmonary nodules, according to their prior probability of malignancy.
计算机断层扫描（CT）偶然发现肺结节的情况日益常见。发现这样一个结节应引发小支气管源性癌的可能性，对此需立即进行切除。然而，对于良性病变应避免进行侵入性诊断程序。这篇综述文章的目的是：（1）分析定义良性结节、高度怀疑恶性的结节和不确定结节的CT标准；（2）分析为明确不确定肺结节特征而进行的补充检查的诊断性能和局限性；（3）回顾评估不确定结节恶性概率的标准；（4）报告弗莱施纳学会根据小的不确定肺结节的恶性先验概率提供的管理新指南。
