摘　　要：目的探讨多层螺旋CT(Multi-slice spiral CT,MSCT)在鉴别良恶性肺孤立性磨玻璃结节(sp GGO)中的价值。方法回顾性分析2015年1月至2017年7月间经MSCT检查有肺孤立性磨玻璃结节的44例患者的MSCT资料,根据病理结果将所有病例分为良性、恶性两组,其中良性结节有13例,包括9例不典型腺瘤样增生(AAH),4例慢性炎症;恶性结节有31例,均为腺癌。观察肺孤立性磨玻璃结节的CT征象特点,包括病灶形态、大小、边缘、实性成分、空气支气管征、空泡征、胸膜凹陷征、瘤肺界面、毛刺征、分叶征、血管集束征,对照病理结果,统计分析CT征象与肺磨玻璃结节良恶性的相关性。结果肺孤立性磨玻璃结节的病灶形态、大小、边缘、实性成分、空泡征、胸膜凹陷征、毛刺征、分叶征、血管集束征与sp GGO的良恶性有相关性,结果具有统计学差异(P<0.05),而两组sp GGO的空气支气管征、瘤肺界面没有统计学差异(P>0.05)。结论 MSCT对肺孤立性磨玻璃结节的良恶性鉴别诊断具有重要价值。Objective To investigate the value of multi-slice spiral CT（ MSCT） signs in differentiating benign and malignant lesions of solitary pulmonary ground-glass opacity（ sp GGO）. Methods From January 2015 to July 2017, the MSCT images of 44 patients with sp GGO in our hospital were retrospectively analyzed. According to the pathological results,these cases were divided into two groups： a benign group（ n = 13） including 9 cases of atypical adenomatous hyperplasia and 4 cases of chronic inflammation and a malignant group（ n = 31） with adenocarcinoma. The CT features of GGO were studied,including the lesion size,shape,edge,solid components,air bronchogram,vacuole sign,pleural indentation,tumor-lung interface,spiculation sign,lobulation sign and vascular convergence sign. The correlation between CT signs and benign and malignant GGOs was analyzed statistically. Results There was statistically significant difference between the benign and malignant GGOs in the lesion size,shape,edge,solid components,vacuole sign,pleural indentation,spiculation sign,lobulation sign and vascular convergence sign（ P〈0. 05）,while there was no statistically significant difference between the benign and malignant GGOs in the air bronchogram and tumor-lung interface（ P〉0.05）. Conclusion MSCT plays an important role in the differential diagnosis of benign and malignant GGOs.
