摘要：

目的:分析胸膜凹陷征(PI)在胸膜下磨玻璃结节(GGN)诊断中的作用,以期提高良恶性胸膜下GGN诊断的正确率及恶性度的分期。方法:回顾性分析70例经病理证实的胸膜下GGN多层螺旋CT(MSCT)表现,采用SPSS 19.0统计软件分析胸膜下良恶性GGN在胸膜凹陷发生率及形态方面是否存在差异。结果:PI在胸膜下良恶性GGN的鉴别中差异有统计学意义(P=0.04),在胸膜下GGN恶性度的分级上差异亦有统计学意义(P<0.001)。结论:PI在胸膜下良恶性GGN的鉴别中起到重要作用,还可在胸膜下GGN恶性度的分级上起指导作用。随着PI发生率的增加、凹陷的深度增加,GGN的恶性度也随之增加。

Objective:To analyze the role of pleural indentation(PI) in the diagnosis of subpleural ground glass nodules (GGN),so as to improve the diagnostic accuracy of benign and malignant subpleural GGN and the stage of malignant degree. Method:Retrospective analysis MSCT findings of 70 subpleural GGN confirmed by pathology was conducted. Differences between benign and malignant GGN were analyzed by using the statistical package of SPSS 19.0. Results:Pleural depression sign was statistically significant in the differentiation of benign and malignant subpleural GGN (P=0.04) and in the classification of subpleural malignancy(P<0.001). Conclusion:Pleural depression sign plays an important role in the differentiation of benign and malignant subpleural GGN, and can also play a guiding role in the classification of subpleural GGN malignancy. With the increase of PI incidence and the depth of depression, the degree of GGN malignancy also increases.
