产前超声诊断胎儿泪囊囊肿

目的探讨产前超声诊断胎儿泪囊囊肿的价值。方法回顾性分析12胎产前超声诊断为胎儿泪囊囊肿的声像图特征,并追踪其妊娠结局。结果产前超声检出12胎胎儿泪囊囊肿,孕周为26～36周,其中双侧3胎,单侧9胎。泪囊囊肿典型超声声像图表现为眼眶内下方见囊性无回声。6胎囊肿产前自行消失;1胎经终止妊娠后确定存在泪囊囊肿;2胎分娩后囊肿自行消失;1胎分娩后因新生儿呼吸窘迫而接受外科手术治疗;2胎失访。结论胎儿泪囊囊肿有其特征性超声表现,正确诊断有利于指导临床工作。

Prenatal ultrasonic diagnosis of fetal lacrimal sac cyst

Objective To explore the value of prenatal ultrasound in diagnosis of lacrimal sac cyst. Methods Prenatal ultrasonic features of 12 fetuses with fetal lacrimal sac cyst were retrospectively analyzed, and the pregnancy outcomes were followed up. Results Twelve fetuses of fetal lacrimal sac cyst were detected with prenatal ultrasound, and their gestational age ranged from 26 to 36 weeks. Among these fetuses, lacrimal sac cyst was bilateral in 3 fetuses and unilateral in 9 fetuses. The typical ultrasonic feature of lacrimal sac cyst was cystic mass without echo in medial and inferior orbit. The lacrimal sac cyst resolved spontaneously prenatally in 6 fetuses. One lacrimal sac cyst was determined after termination of pregnancy. Two lacrimal sac cyst resolved spontaneously after delivery. The lacrimal sac cyst disappeared in one newborn after receiving surgical intervention for respiratory distress syndrome after delivery. Two fetuses were lost during follow-up. Conclusion Fetal lacrimal sac cyst has characteristic ultrasonic appearances. Correct diagnosis is valuable for guiding clinical work.
