摘　　要：目的探讨细支气管腺瘤(BA)的多层螺旋CT(MSCT)征象。方法回顾性分析经手术病理证实的9例BA患者的影像学资料并复习文献。结果9例BA中,8例周围型,距离胸膜≤5mm,其中4例紧贴胸膜,1例中央型;位于右肺上叶3例,右肺中叶2例,右肺下叶2例,左肺下叶2例;实性结节型5例,磨玻璃结节型2例,囊腔型2例;2例实性结节非静脉侧边缘模糊,1例磨玻璃结节灶内线网状影伴边缘模糊;2例胸膜轻度凹陷,7例血管进入或贴附于病变边缘,3例伴血管增粗;8例经过2~48个月随访,1例囊腔型伴阻塞性炎症、炎症吸收,1例实性结节型增大伴空泡出现,6例随访无变化,1例中央型CT检查后直接手术。结论BA主要为肺外周的结节影,以紧贴胸膜及距离胸膜≤5mm多见,以实性结节表现多见,也可呈磨玻璃结节及囊腔型,部分结节非静脉侧边缘模糊或炎性表现,少数结节随访过程增大,伴或不伴小空泡。Objective To summarize the multi slice spiral computed tomography(MSCT)features of bronchiolar adenoma(BA).Methods The imaging data of 9 cases of BA confirmed by surgery and pathology were analyzed retrospectively,and relevant literature was also reviewed.Results Among the 9 cases of BA,there were 8 cases with peripheral BA(away from the pleura<5 mm)including 4 cases close to the pleura and 1 case in central area.BA were located in the superior lobe of the right lung in 3 cases,the middle lobe of the right lung in 2,the inferior lobe of the right lung in 2,and the inferior lobe of the left lung in 2.Five cases were solid nodules,2 were ground-glass nodules and other 2 were cystic cavity nodules.In 2 cases of the solid nodules,the boundary on the non-venous side was blurred.In the 1 case of the ground-glass nodule,linear and reticular shadows were observed in the lesion,accompanied by a blurred boundary.2 nodules had mild pleura indentation,and other 7 nodules were found blood vessels entering into or adhering to the lesion,3 of which were accompanied by vascular thickening.In 8 cases with 2-48 month followed up,1 cystic cavity nodule was accompanied by obstructive pneumonia and then inflammatory absorption,l solid nodule enlarged accompanied by the appearance of vacuoles,and the rest 6 had no changes.One central type nodule was operated after the CT examination.Conclusion BA are mainly manifested as peripheral nodules of the lung,mostly close to the pleura and away from the pleura≤5 mm.Most BA are solid nodules,and sometimes are ground-glass or cystic cavity nodules.Some nodules show blurred boundaries or inflammation on the non-venous side,and few nodules increase during follow-up,with or without small vacuoles.
