Correlation between 3D Ultrasound Appearance and Postnatal Findings in Bilateral Malformations of the Fetal Hands

Malformations of the hand have an incidence of 1 in about 1,500 births. Ultrasound diagnosis and classification of the anomaly is not always easy because of the various positions taken by the hand. We describe the case of a 23-year-old patient with a fetus affected by a symmetrical and bilateral hand oligodactyly associated with deformities of the other fingers. 3D ultrasound evaluation allowed an exact prediction of the malformation and showed perfect correspondence with postnatal findings. The case illustrates the contribution of 3D ultrasound to the evaluation of fetal limb anomalies.
