Abstract

6 of 19 fetuses with trisomy 18 confirmed by late karyotyping in the third trimester were found to have an enlarged cisterna magna (10 mm or more). For trisomy 18 conceptuses, in that location is a meaning excess of females in both fetuses and livebirths; however, we plant this ratio to be reversed in the third-trimester trisomy 18 fetuses with an enlarged cisterna magna (5 males vs. one female person), indicating males are more likely to have this associated defect. Each of the 6 cases was associated with other trisomy markers including intrauterine growth retardation and polyhydramnios. Since a pregnant proportion of pregnancies may escape early prenatal intendance and some potentially detectable fetal abnormalities may be missed on early ultrasound and/or past maternal serum screenings, prenatal detection of an enlarged cisterna magna associated with intrauterine growth retardation and/or polyhydramnios in late gestation should prompt complete genetic counseling, rapid karyotyping and a careful search for other built anomalies.
