A Gravida 2, Para I was scanned at 31 weeks of gestation. The fetus showed:
an atrio-ventricular septal defect,
a short forearm in one of the upper limbs
intercalaray hemimelia (probably only the ulna was present)
radial deviation of the thumb on 2D images.
The 3D images demonstrated the characteristic shortened forearm and the radial deviation of the wrist and hand. The rendering of fingers was technically difficult. The patient opted for termination of the pregnancy. The postnatal photographs were not available. However, the external features were confirmed by the obstetrician. No karyotyping or fetal blood sampling was done. The following are the ultrasound images:
