胎儿先天性肺囊性腺瘤样畸形的MRI诊断

摘要

目的:探讨MRI对胎儿先天性肺囊性腺瘤样畸形(CCAM)的诊断价值.方法:分析34例经产后病理证实的CCAM的MRI表现.结果:34例MRI扫描示,病灶位于左侧12例,右侧22例.出生后经胸部CT增强扫描比较,1例未发现病灶,2例误诊为先天性肺隔离症,1例误诊为先天性肺气肿.结论:MRI能很好显示胎儿CCAM的位置和形态,对该病的诊断具有较高价值.%Objective:Discussing the value of MRI in the diagnosis of congenital cystic adenomatoid malformation of fetal lung. Methods:34 cases of congenital cystic adenomatoid malformation were analyzed by the use of MRI. Results:In 34 cases of MRI examination,12 cases were on the left side,22 cases were on the right side,and 5 cases of unilateral performed total lobectomy. After the birth,CT scan found that 1case was no lesion,2 cases were misdiagnosed as pulmonary sequestration,and 1 case was misdiagnosed as congenital emphysema. Conclusion:MRI can well display the location and shape of the fetal CCAM,and it has high value for the diagnosis of fetal CCAM.
