A 41-year-old G4 P3 with unremarkable family or personal history was referred to our center for the ultrasound scan at 16 weeks. We have seen a large mass at the level of the thoraco-spinal region. There was no amniotic fluid and we did not see urinary bladder. We could not detect fetal kidneys and there was no renal arteries branching from the abdominal aorta.
Ductus venosus showed reverse flow. Parents wished for the pregnancy termination.
Fetus showed the signs of oligohydramnios sequence. There were abnormal limb positions, abnormal face - flat face with low set ears. There was a spina bifida at the thoracic region. Unfortunatelly, parents did not agree on the autopsy.
Images 1,2: Image of the fetal head and abdomen. Note complete anhydramnios.
Images 3,4: Image 3 shows a transverse view of the fetal abdomen, kidneys are not visible. Image 4 shows fetal femur.
Images 5,6: Arrows on image 5 indicate possible spina bifida. It is technically difficult to make an accurate diagnosis due to anhydramnios.
Images 7,8: 3D-images showing sagittal view of the fetus.
Images 9: Abnormal ductus venosus, reverse flow.
Images 10 - 13: Images of the fetus after pregnancy termination, note the abnormal limb positions and deformities, flat face, low set ears.
