摘要
目的:探讨先天性肺囊性腺瘤样畸形的CT表现。方法:回顾性分析15例先天性肺囊性腺瘤样畸形的CT表现,并与手术、病理结果对照。结果:15例先天性肺囊性腺瘤样畸形CT表现为大囊型10例、小囊型5例。病理检查见囊腔为异常增生的管腔或腺样结构,壁内被覆假复层纤毛柱状上皮8例,纤毛柱状及立方上皮7例;囊周可见平滑肌及弹性纤维环绕,15例囊壁内均未见软骨成分及腺体。结论:CT检查是诊断先天性肺囊性腺瘤样畸形的可靠方法,根据CT表现可推测其病理分型。
Objective：To study the CT manifestations of congenital cystic adenomatoid malformation（CCAM） of the lung.Methods：CT findings in 15 patients with CCAM were retrospectively reviewed,and correlated with the surgical and pathological reaults.Results：CT manifestations of 15 cases with CCAM included large cystic type in 10 cases and small cystic type in 5 cases.The pathologic findings showed that the cyst was paraplasmic glandular or bronchiolar structures,cyst wall was lined with ciliated pseudostratified columnar epithelium in 8 cases and lined by cuboid to columnar epithelium in 7 cases.The cyst wall contained smooth muscle and elastic tissue.Cartilage plates were not present in all cases.Conclusion：CT is a reliable method in diagnosing CCAM.Based on imaging manifestations observed on CT,the pathologic type of CCAM might be predicted.
