摘要：

目的探讨纯磨玻璃密度(pGGO)结节浸润性肺腺癌的CT特点。方法根据2011年多学科肺腺癌分类(IASLC/ATS/ERS分类),收集经手术病理确诊为肺腺癌并且CT表现为pGGO结节(≤3cm)的88例患者(94个病变),其中浸润性肺腺癌37例(38个病变),结合临床和病理资料,分析结节的瘤肺界面、病灶边缘(分叶、毛刺)、内部结构及邻近结构。结果 38个浸润性肺腺癌结节最大径0.7～3.0cm,平均(1.75±0.46)cm,其中结节直径<1cm者3个,1～2cm者25个,>2cm者10个。所有结节边界均较清楚,结节出现分叶31个,毛刺11个,空泡征28个,形成空腔5个,胸膜凹陷征14个,血管集束征28个。18个结节局部或整体密度增高,其中局部密度增高12个,整体密度增高6个。手术病理证实贴壁生长腺癌27个,微乳头腺癌2个,腺泡样癌4个,乳头型腺癌2例,实性腺癌3例。结论 pGGO肺腺癌结节中,CT表现为空泡征、瘤肺界面清晰、血管集束征提示浸润性肺腺癌可能。
