摘　　要：目的:分析肺内孤立性小结节的CT表现,探讨肺内孤立性小结节良恶性的鉴别诊断。方法:回顾性分析2010年1月-2013年1月经病理证实的50例肺内孤立性小结节患者的CT检查资料。结果:恶性病变32例,全部为周围型肺癌;良性病变18例,包括结核球7例、炎性结节8例、肺错构瘤3例。肺癌病灶的分叶征、毛刺征、胸膜凹陷征、小空洞征发生率高于其他种类(P<0.05)。结论:CT对肺孤立性小结节有较高的诊断价值,是区分良恶性孤立性肺结节的有效方法。Objective： To analyze manifestations of CT in solitary pulmonary nodules, to determine if solitary pulmonary nodules（SPN） were benignant or malignant.Method： Researchers retrospectively analyzed the data of 50 eases with solitary pulmonary nodules from Jan 2010 to Jan 2013.Those cases were confirmed by pathology.Result： Totally 32 patients with malignant SPN were lung cancer.There were 18 cases with benign SPN, including 7 cases with tuberculoma, 8 cases with inflammatory pseudotumor of the lung, and 3 cases with hamartoma.Incidenee rates of some signs in lung cancer, including lobulation signs, spieulation signs, pleural retraction signs, small cavity syndromes, were higher than others（P〈0.05）.Conclusion： CT has high value in the diagnosis of SPN.It is an effective method to determine ffSPN Was benignant or malignant.
