摘要
目的:探究囊腔类肺癌的MSCT征象与不同病理类型的相关性,提高诊断率及病理基础的认识。方法:回顾性分析经手术病理证实的50例囊腔类肺癌的MSCT征象及病理特征,均为腺癌,根据病理类型不同分为原位癌组、微浸润腺癌组及浸润性腺癌组,有随访病例评价CT变化特点。结果:50例均为周围型肺癌,CT征象比例>50%的有:类圆形或圆形(84%)、磨玻璃征(58%)、蜂窝征(64%)、分叶征(60%)、囊壁薄(82%)、血管集束征(50%)、形态学Ⅳ型(58%)。原位癌组13例,微浸润腺癌组15例,浸润性腺癌组22例。磨玻璃征、分叶征、毛刺征、腔内分隔、壁结节及血管穿行征与三组病理类型差异有统计学意义(P<0.05);随访8例有变化。结论:囊腔类肺癌以腺癌多见,MSCT征象有特殊性且与病理类型有相关性,结合动态随访有助于诊断。
Purpose: To investigate the correlation between MSCT signs and pathological types of lung cancer associated with cystic airspaces, and to improve the diagnosis and awareness of the pathological basis of lung cancer associated with cystic airspaces. Methods: MSCT and pathological features of 50 cases of lung cancer associated with cystic airspaces confirmed by surgery and pathology results were retrospectively analyzed. According to the pathological types of adenocarcinoma, these cases were divided into three groups: adenocarcinoma in situ group, minimally invasive adenocarcinoma group and invasive adenocarcinoma group. Results: All of the cases were peripheral lung cancer. The CT signs shown in more than 50% cases were: round/oval shape (84%) , ground glass sign (58%), honeycomb sign (64%), lobulation sign (60%), thin-walled cystic (82%), vascular convergence sign (50%) and morphological type Ⅳ (58%). Of all the cases, 13 cases were adenocarcinoma in situ, 15 were minimally invasive adenocarcinoma, 22 were invasive adenocarcinoma. There were statistical differences between pathological types of three groups in ground glass opacity, lobulation, spiculation, septum inside airspace, mural nodules and blood vessel passing (P<0.05). MSCT signs of 8 cases of lung cancer associated with cystic airspaces were changed on follow-up exam. Conclusion: Lung cancer associated with cystic airspaces is more common in adenocarcinoma, the CT signs are special and have correlation with the pathological type. Dynamic follow-up exam is helpful for the diagnosis.
