成人先天性肺囊性病变影像学分析

Imaging characteristics of adult congenital cystic lung lesions

目的:探讨成人先天性肺囊性病变的影像学特点以及与肺癌的关系。方法:对23例经外科手术切除病理证实的成人先天性肺囊性病变,进行影像学分析,并系统复习文献。结果:支气管源性肺囊肿12例(52.2%);先天性囊性腺瘤样畸形5例(21.7%),其中1例伴发黏液性原位腺癌(LASLC/ATS/ERS 2011年版肺癌新分类),1例伴发鳞癌;肺隔离症6例(26.1%)。结论:成人先天性肺囊性病变最常见类型,是支气管源性肺囊肿。先天性囊性腺瘤样畸形少见,诊断过程中如怀疑先天性囊性腺瘤样畸形,应警惕发生肺癌的危险。

Objective：To study the imaging characteristics of adult congenital cystic lung lesions and correlation with lung cancer. Methods：Retrospectively studied imaging characteristics of 23 cases with congeni- tal cystic lung lesions proved pathologically. Restflts： 12 cases of bronchogenic cysts（52. 2% ）, 5 cases of con- genital cystic adenomatoid malformation （CCAM） （21.7%）, 6 cases of bronchopulmonary sequestration （26. 1% ）. One case of CCAM was associated with mucinous adenocarcinoma in situ （LASLC/ATS/ERS 2011 ）, another case of CCAM was associated with squamous cell carcinoma. Conclusion：Bronchogenic cyst is common in adult congenital cystic lung lesion, CCAM is quite rare. Carcinoma should be considered when diag- nosis is CCAM.
