目的与方法分析小儿先天性肺囊性腺瘤样畸形congenital cystic adenomatoid malformation,CCAM及其合并其他先天畸形的CT表现,加强对本病的认识,提高诊断准确率。回顾性分析15例小儿先天性肺囊性腺瘤样畸形的CT征象,肺部常规5mm层厚扫描,在16层螺旋CT行0.8mm后处理重组,记录病变的特点及其周围组织改变。结果 15例病例CT均能显示肺内数目不等的薄壁囊腔,其中10例最大薄壁囊腔直径超过2cm,5例为直径1-2cm的薄壁小囊组成,按发生部位分类,发生在右肺7例,发生在左肺8例,按合并其他疾病分类,6例合并漏斗胸,6例合并肺炎,1例合并脂肪肝及肺脓肿,1例合并肺炎及胸腔积液,1例单纯肺内囊性改变。结论肺内大小不等的薄壁囊腔为先天性肺囊性腺瘤样畸形的典型表现,其伴发的其他畸形及病变在一定程度上可促进我们对本病的认识,提高诊断准确率。
Objective To investigate the CT findings of congenital cystic adenomatoid malformation, congenital cystic adenomatoid malformation and other congenital malformations in children with congenital cystic adenomatoid malformation. To improve the diagnosis of this disease and improve the diagnostic accuracy. CT findings of 15 cases of congenital cystic adenomatoma of pulmonary cystadenoma were retrospectively analyzed. The lungs were routinely scanned with 5 mm slice thickness. After 16-slice spiral CT was performed 0.8mm post-processing and reorganization, the characteristics of lesions and the surrounding tissue changes were recorded. Results Fifteen cases of CT showed thin-walled cysts with different numbers in the lung. Among them, 10 cases with the largest thin-wall cysts exceeded 2 cm in diameter and 5 cases were thin-walled cysts with 1-2 cm in diameter. According to the site of occurrence, Occurred in the right lung in 7 cases, occurred in the left lung in 8 cases, according to the merger of other diseases, 6 cases with funnel chest, 6 cases of pneumonia, 1 case of fatty liver and lung abscess, 1 case of pneumonia and pleural effusion, 1 Cases of simple cystic lung changes. Conclusions The thin-wall cysts with different sizes in the lung are the typical manifestations of congenital cystic adenomatoid deformity. The other deformities and lesions associated with it may promote our understanding of the disease and improve the diagnostic accuracy.
