ultrasound diagnosis of fatal anomalies

OMPHALOCELE
Fig. 6.16 Omphalocele. Same fetus at 13 + 1 weeks.
Oblique section through the fetal abdomen at the
level of hernial canal and lower fetal thorax, with a
section of fetal heart. The hernial canal appears
much smaller than the hernial sac, with echogenic
structures. Transabdominal chorionic villous sampling
(TA-CVS) showed a normal karyotype. There
were no other anomalies.
Fig. 6.17 Omphalocele. Same fetus at 13 + 1 weeks.
The transducer has been tilted caudally to obtain an
oblique view of the umbilical vessels next to the fetal
urinary bladder. Spontaneous abortion occurred at
16 weeks. “Isolated hepatic tissue” was found in the
omphalocele.
