Over a 22-month period, 1045 second-trimester pregnancies were evaluated with ultrasound for the presence of choroid plexus cysts. The frequency of fetal choroid plexus cysts was 3.6% (38/1045). The outcome of the 38 fetuses possessing choroid plexus cysts was as follows: One fetus had triploidy, an occurrence not previously reported; one fetus had hydrocephalus and a normal karyotype; the other 36 fetuses were born normal. Our data were combined with those of previously reported series of fetal choroid plexus cysts to determine if chromosomal analysis is necessary in all fetuses possessing a choroid plexus cyst.
在22个月的时间里，对1045例孕中期妊娠进行了超声检查，以确定是否存在脉络丛囊肿。胎儿脉络丛囊肿的发生率为3.6%（38/1045）。38例患有脉络丛囊肿的胎儿的结局如下：1例胎儿为三倍体，此前未见报道；1例胎儿患有脑积水且核型正常；其他36例胎儿出生正常。我们的数据与先前报道的胎儿脉络丛囊肿系列数据相结合，以确定是否有必要对所有患有脉络丛囊肿的胎儿进行染色体分析。
