胎儿脉络丛囊肿(choroid plexus cysts,CPCs)是一种常见的胎儿中枢神经系统异常,其发病率达1%~4%,通过妊娠早中期的产前超声检查可诊断。CPCs可能和胎儿的某些染色体和神经系统异常有关,尤其是18三体综合征和Aicardi综合征。大量研究表明,这种相关性还受到许多其他因素的影响,故临床医师发现CPCs时需考虑到胎儿是否合并其他畸形或异常,联合妊娠期母亲血清筛查风险性结果以及CPCs的特点等因素,对妊娠妇女进行个体化的风险评估,并予以恰当的处理。
Choroid plexus cysts (CPCs), a common fetal central nervous system abnormality, have a prevalence of 1% to 4%, which can be diagnosed by prenatal ultrasound in early and middle gestation. CPCs may be associated with some chromosomal and neurological abnormalities in the fetus, particularly Trisomy 18 and Aicardi syndrome. Numerous studies have shown that this correlation is also affected by many other factors, so clinicians found that CPCs should be considered when the fetus with other malformations or abnormalities, combined with gestational maternal serum screening risk characteristics and characteristics of CPCs and other factors, Pregnant women are individually assessed for risk and appropriately treated.
