This is a 21-year-old primigravida, referred to our unit at 27 weeks due to a discordance between the gestational age and the uterine measurement and poor fetal movements. An arthrogryposis or pterygium syndrome was suspected. In our evaluation the ultrasound findings were:
severe growth restriction
joint contractures in hands
macrocephaly without hydrocephaly
single umbilical artery
Amniotic fluid index in the lower limit for gestational age
placenta slightly hyperechogenic.
An aneuploidy was suspected. We recommend a cordocentesis to confirm the diagnosis and the karyotype was 69,XXX. The baby was stillborn at 39 weeks (1350g).
Note the joint contractures
Note the severe growth restriction (the discordance between the gestational age and the femur length)
Joint contractures in hands
Single umbilical artery and the hyperechoic placenta
