【摘要】：目的探讨表现为纯磨玻璃结节(pGGN)的肺微浸润腺癌(MIA)与浸润性腺癌(IAC)的CT鉴别诊断。方法回顾性分析经手术病理证实的表现为pGGN的32例MIA与66例IAC的临床及CT资料,分析病例的年龄、性别及病灶最大径、密度、形态、边缘、内部及邻近结构改变等CT征象,并进行统计学分析。结果 MIA和IAC在年龄、性别方面差异无统计学意义(P值均0.05);两组CT显示病灶的最大径、密度、形态、瘤-肺界面清晰方面差异无统计学意义(P值均0.05),分叶征、毛刺征、空气支气管征、pGGN内支气管呈扭曲、扩张样改变及血管集束征两组差异有统计学意义(P值均0.05)。结论当pGGN病灶伴有分叶征、毛刺征、空气支气管征、pGGN内支气管呈扭曲、扩张样改变及血管集束征时,其为IAC的可能性更大。
[Abstract]:Objective to investigate the CT differential diagnosis of pulmonary microinvasive adenocarcinoma (MIA) and invasive adenocarcinoma (IAC) with pure ground-glass nodules (pGGN). Methods the clinical and CT data of 32 cases of MIA and 66 cases of IAC confirmed by operation and pathology were analyzed retrospectively. The age, sex, maximum diameter, density, morphology, edge, internal and adjacent structure of the lesions were analyzed. Statistical analysis was carried out. Results there was no significant difference in age and sex between MIA and IAC (P 0.05), but there was no significant difference in the maximum diameter, density, morphology, clear tumor-lung interface between the two groups (P 0.05), lobulation sign and burr sign. There were significant differences between the two groups in air bronchus sign (P < 0.05), dilatation-like change (P < 0.05) and vascular cluster sign (P < 0.05). Conclusion when the lesion of pGGN is accompanied by lobulation, burr sign and air bronchus sign, the possibility of IAC is higher when the bronchus of pGGN is distorted, dilatation like change and vascular cluster sign.
