【摘要】：目的:探讨肺腺癌浸润前病变的CT表现。方法:回顾性分析2011年3月-2016年12月经手术病理证实的45例肺腺癌浸润前病变患者的临床和CT资料,其中不典型腺瘤样增生(AAH)10例、原位癌(AIS)35例,主要分析指标包括病灶分布、大小、密度、分叶征、毛刺征、空泡征、充气支气管征、肿瘤微血管成像征和胸膜凹陷征。结果:35例表现为纯磨玻璃密度结节、10例为部分实性成分磨玻璃密度结节;AAH组和AIS组中病灶直径分别为(10.15±3.72)和(11.73±4.58)mm,平均CT值分别为(-514±70.66)和(-477.2±168.08)HU,两组间差异均无统计学意义(P0.05)。CT征象中以肿瘤微血管成像征最多见(出现率为68.9%),其次是分叶征、空泡征(均为26.7%),充气支气管征最少见(4.4%);两组间各征象的差异均无统计学意义(P0.05)。结论:肺腺癌浸润前病变的CT征象中肿瘤微血管成像征具有一定特异性,CT形态学征象并不能准确鉴别不典型腺瘤样增生和原位癌。
[Abstract]:Objective: to investigate the CT findings of preinvasive lesions in lung adenocarcinoma. The clinical and CT data of 45 patients with preinvasive lesions of lung adenocarcinoma confirmed by surgery and pathology from March 2011 to 2016 were analyzed retrospectively. There were 10 cases of atypical adenomatous hyperplasia (AAH) and 35 cases of carcinoma in situ (AIS). The main indexes included distribution, size, density, lobulation sign, burr sign, vacuole sign and inflatable bronchus sign. Results 35 cases showed pure ground glass density nodules, 10 cases were partial solid glass density nodules. The diameter of lesion in AAH group and AIS group was 10.15 卤3.72) and 11.73 卤4.58 mm respectively. The mean CT values were -514 卤70.66) and -477.2 卤168.08 Hu, respectively. There was no significant difference between the two groups in the signs of tumor microvessel imaging (68.9%), followed by lobulation sign and vacuole sign (26.7%). The infrequent inflatable bronchus sign was 4.4T; There was no significant difference in each sign between the two groups (P 0.05). Conclusion: the CT signs of preinvasive lesions of lung adenocarcinoma have a certain specificity. Ct morphologic findings do not accurately distinguish atypical adenomatous hyperplasia from carcinoma in situ.
