Trisomy 18
Russia

Case report
33-year-old (G2P1) was sent to our unit for second trimester scan. First trimester scan was done with NT-3,2 mm (above 95 percentile). Calculated risk for trisomy 18 was 1:105. Although parents refused karyotyping and opted for continuation of the pregnancy.
Our scanning at 21 and 30 weeks of pregnancy revealed atrioventricular septal defect, choroid plexus cyst (at 21 weeks), mild micrognathia, umbilical cord pseudocysts, clenched fists and overlapping fingers and intrauterine growth restriction.
