摘　　要：目的 探讨细支气管腺瘤(BA)的CT征象并对误诊原因进行分析.方法 回顾性收集经手术病理证实的 8 例 BA患者胸部CT影像资料、病理学资料并结合相关文献进行分析.结果 8 例患者均无明显临床症状,其中左肺下叶 3 例、右肺下叶 4 例,右肺中叶 1 例,且均位于肺外周(结节与胸膜距离 5~20 mm);形态不规则 5 例,边缘模糊 5 例;实性结节 4 例,混合磨玻璃结节(mGGN)3 例,纯磨玻璃结节(pGGN)1 例,其中见毛刺征 4 例、空泡征 3 例、分叶征 3 例、异常充气支气管征 1 例、胸膜凹陷征 2 例.结论 BA的CT表现多样,空泡征及瘤-肺界面模糊较具特征性,对BA与早期肺癌的鉴别诊断具有一定的参考价值.Objective To investigate the CT features of bronchiolar adenoma(BA)and the causes of misdiagnosis.Methods A retro-spective analysis of chest CT imaging data and pathological data was done in conjunction with relevant literature on eight patients with BA diagnosed by surgical pathology.Results There were no obvious clinical symptoms in any of the eight patients.Among them,three cases had nodules in the lower left lobe,four in the lower right lobe,and one in the middle right lobe,all of which were located in the peripheral area of the lungs(the distance between the nodules and the pleura ranged from 5 mm to 20 mm).The nodules showed irreg-ular shape in five cases and blurred edge in five cases.Four cases had solid nodules,three had mixed ground-glass nodules(mGGN),and the other one had pure ground-glass nodules(pGGN).The burr sign was observed in four cases,the vacuolar sign in three cases,the lobular sign in three cases,abnormal bronchial inflation sign in one case,and the pleural depression sign in two cases.Conclusion A variety of manifestations of BA can be seen on CT images,and the vacuolar sign,as well as the fuzzy appearance of the interface between the tumor and lung,may be more visible,which may be helpful for the differential diagnosis between BA and early lung cancer.
