摘要
目的探讨胎儿囊性淋巴管瘤的产前MRI特点及诊断价值。方法回顾性分析我院2008年8月—2010年4月经超声检查怀疑胎儿淋巴管瘤并有完整资料的4例孕妇的常规MR图像,孕妇年龄24~30岁,孕龄31＋3周~38＋1周,观察分析其MRI特点。结果 4胎经MRI诊断为胎儿囊性淋巴管瘤,均由产后病理得到证实;MRI显示病变为单囊状或内含分隔、呈多囊状的长T1长T2信号,病变部位以颈部多见,瘤体直径1.73~10.63 cm。结论产前MRI能明确诊断胎儿淋巴管瘤。
Objective To observe the MRI characteristics and the value of prenatal diagnosis for fetal cystic lymphangioma.Methods Conventional MRI of 4 fetus with suspected lymphangioma and complete image data were retrospectively reviewed.Pregnant women aged 24—30 years,with the gestational ages of 31＋3 weeks—38＋1 weeks.Results All 4 fetus were diagnosed as cystic lymphangioma with MRI,which was then proved pathologically.MRI findings of cervical lymphangioma in fetus were as follows： Single or polycystic with septations mass with low T1 and high T2 signal intensity on unilateral or bilateral neck,tumor size ranging from 1.73 to 10.63 cm in diameter.Conclusion MRI is valuable for prenatal diagnosis of cervical lymphangioma in fetus.
