【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。更多还原

【Abstract】 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.更多还原
