【摘要】目的:探讨肺腺癌纯磨玻璃密度结节(pure ground-glass opacity,pGGO)内部CT影像学特征.方法:回顾性分析156个手术病理证实的pGGO结节内部CT影像特点.所有pGGO结节中浸润前病变58个(包括不典型腺瘤样增生及原位腺癌)、微浸润腺癌32个和浸润性腺癌66个.pGGO结节内部CT影像特征包括病变密度均匀/不均匀、空泡征、空气支气管征及病变内走行血管异常改变(血管扩张、扭曲、僵直).结果:pGGO结节中密度不均、病变内血管异常改变在3种不同病理分型中差异有统计学意义(x2=7.452,P=0.024;(x2=22.615,P＜0.001),随着结节浸润程度的增加,病变密度不均及其内血管异常改变的发生率随之增加;空气支气管征的发生率亦随病变浸润程度的加深而增高,但其仅对于浸润前病变与浸润性病变(包括微浸润腺癌和浸润性腺癌)的鉴别诊断有价值(x2=4.868,P=0.027).结论:pGGO结节内部密度不均、血管异常改变对肺腺癌不同病理类型的鉴别具有一定的价值.%Objective To discuss the pathological classification and lesion's inner imaging features of lung adenocarcinoma presented as pure ground-glass opacity.Methods CT imaging features of 156 pGGO lesions which confirmed by surgery and pathology were analyzed in retrospectively.There were 58 lesions of pre-invasive (including atypical adenomatous hyperplasia and adenocarcinoma in situ),32 lesions of
