Trisomy 9 is a lethal chromosomal abnormality that rarely progresses beyond the second trimester of pregnancy. Multiple central nervous system anomalies, including bifid choroid plexus, ventriculomegaly, and Dandy-Walker malformation, associated with multicystic dysplastic kidney disease in a trisomy 9 fetus are reported. The prenatal ultrasound diagnosis has been aided by novel three-dimensional ultrasound software.
9号染色体三体是一种致死性染色体异常,很少能在妊娠中期之后继续发展。据报道,一名9号染色体三体胎儿存在多种中枢神经系统异常,包括脉络丛分裂、脑室扩大和Dandy-Walker畸形,并伴有多囊性发育不良肾病。新型三维超声软件辅助了产前超声诊断。
