摘　　要：目的:分析肺部先天性囊性病变的CT表现,探讨其CT诊断价值。方法:回顾性分析17例经手术病理证实的肺部先天性囊性病变(先天性肺囊肿9例;先天性大叶性肺气肿2例;先天性囊性腺瘤样畸形3例,其中1例合并漏斗胸;先天性肺隔离症3例,均合并有肺囊肿;)的CT表现,包括病变的位置、大小、形态、边缘、数量、内部结构等。结果:肺囊肿多位于两下肺,单发多见,单发者形态规则,密度均匀,边缘清晰,多发囊肿形态不规则。先天性大叶性肺气肿(CLE)多位于两上肺叶,内含气体和肺纹理,边缘清晰。先天性囊性腺瘤样畸形(CCAM)形态不规则,内含气体、索条状结构。肺隔离症多位于纵隔旁,可含有气体、液体和软组织多种成分。结论:结合肺部先天性囊性病变的部位、大小、囊肿的数目、形态等CT表现,有助于提高病变的术前诊断准确率。Objective：To analyze the CT manifestations of congenital cystic lung lesions so as to explore the diagnostic value of CT.Methods：17 patients with pathologically proven congenital cystic lung lesions,which consisted of 9 cases of congenital lung cyst;2 cases of congenital lobar emphysema,3 cases of;congenital cystic adenomatoid malformation（1 case with funnel chest） and 3 cases of congenital pulmonary sequestration associated with lung cysts,were enrolled in this work.The CT findings of these 17 patients,including the lesion location,size,shape,margin,quantity,the internal structure,etc.,were retrospectively analyzed.Results：Most of lung cysts were located in both lower lungs,more common in single with shape formulated,homogeneous density and clear edge,while,multiple cysts were irregular.Most of congenital lobar emphysema were located in both upper lungs containing gas lung-markings,and clear edge.The shape of congenital cystic adenomatoid malformation was irregular containing gas and cable strip structure.Congenital pulmonary sequestration was located adjacent to the mediastinum,which may contain gas,liquid,soft tissue,and other ingredients.Conclusion：Combining congenital cystic lung lesions with the location,size,number of cysts and shape in CT can help to improve the accuracy of preoperative diagnosis of the diseases.
