【摘要】：目的探讨CT表现为混合磨玻璃结节的肺原位腺癌(AIS)、微浸润腺癌(MIA)和浸润性腺癌(IAC)中实性成分的CT表现及病理特征,分析肺混合磨玻璃结节中实性成分对AIS、MIA和IAC的定性诊断价值,为临床选择治疗方法提供参考。资料与方法回顾性分析CT表现为混合磨玻璃结节、并经手术病理证实的18例AIS、53例MIA及28例病灶最大径≤2 cm的IAC患者,分析3组病灶中的实性成分的CT表现,并与病理结果进行对照。结果 AIS病灶中实性成分以点状或多边形多见,大小分布面较广,实性结节常单发(17例,94.44%),位于病灶中心(14例,77.78%),边界清晰(16例,88.89%),与同层面血管密度相仿(13例,72.22%);MIA实性成分以圆形及椭圆形居多(33例,62.26%),大小≤5 mm(48例,90.57%),呈偏心性多点分布(45例,84.90%),边界欠锐利(40例,75.47%),密度稍低于同层面血管(34例,64.15%);IAC病灶中实性成分以不规则形多见(21例,75.00%),大小5 mm(24例,85.71%),呈偏心性生长(20例,71.43%),并呈多结节融合,边界欠锐利(15例,53.57%)。3组病灶中的实性成分CT表现差异均有统计学意义(P0.01)。结论根据肺混合磨玻璃结节中实性成分在CT影像上的不同表现,能在一定程度上预测肺混合磨玻璃结节的病理分型和预后,并指导临床处理原则。
[Abstract]:Objective to investigate the CT features and pathological features of solid components in mixed milled glass nodules (AISA) and invasive adenocarcinomas (IAC), and to analyze the diagnostic value of solid components in mixed milled glass nodules for AISMIA and IAC.To provide a reference for clinical selection of treatment methods.Materials and methods CT findings of mixed ground-glass nodules were retrospectively analyzed in 18 patients with MIA and 28 patients with IAC whose maximum diameter was less than 2 cm. Ct findings of solid components in 3 groups were analyzed.The results were compared with pathological results.Results the solid components of AIS lesions were mostly punctate or polygonal, and the size of the lesions was very wide.瀹炴，
