摘　　要：目的:总结分析28例胎儿颈部囊性包块的MRI特点,提高产前MRI诊断水平。方法:搜集经产前超声检查发现的28例胎儿颈部囊性病变,于3d内行胎儿颈部MRI检查,回顾性分析28例病例的临床及影像资料。结果:28例胎儿颈部囊性包块中16例位于左侧,3例位于颈部正中,9例位于右侧;其中6例跨越中线;11例囊内有分隔。28例胎儿颈部囊性包块内信号特点均表现为T1WI低信号、T2WI高信号,2例在新生儿期T1WI信号不同程度增高,内可见气液平面和液液平面。经手术或引产后病理证实确诊为淋巴管瘤15例(其中1例位于颈前体积较小的淋巴管瘤出生后自然消退),腮裂囊肿8例,甲状舌管囊肿1例,食道闭锁4例。结论:胎儿MRI检查能够弥补胎儿超声检查的不足,获得更多产前诊断信息。Objective:The aim of this study was to analyze the MRI features of 28 cases of fetal cervical cystic mass and to improve the prenatal MRI diagnostic level.Methods:28 patients with fetal cervical cystic lesions found by prenatal ultrasound in Hubei Maternal and Children's Hospital from October 2014 to October 2021 were examined by fetal neck MRI within three days and analyzed retrospectively.Results:Among 28 cases of fetal cervical cystic mass,15 cases were located in the left side,3 cases in the middle of the neck,and 9 cases in the right side.Of all the cases,six cases were across the midline,and 11 cases were presented as multilocular masses.The signal characteristics showed as low signals on T 1WI and high signals on T 2WI.In 2 cases,the T 1WI signal increased in varying degrees during the neonatal period,and the gas-fluid and fluid-fluid levels could be seen.In the follow-up after birth,15 cases of cystic hygroma(including 1 case of cystic hygroma located in the front of the neck with a small volume subsided naturally after birth),8 cases of branchial cleft cysts,1 case of thyroglossal duct cyst and 4 cases of esophageal atresia confirmed by operation or pathology after induced labor.Conclusion:Fetal MRI examination can be a remedy for the downsides of fetal ultrasound examination and obtain more prenatal diagnostic information.
