Recently, the largest series of triploidy to date was reported, describing the antenatal US scan features in great detail. However postmortem findings were not included. The current study compared antenatal US scan features with postmortem findings to facilitate the sonographic diagnosis and define its limitations.
The most common fetal defects-ventriculomegaly, syndactyly, atrioventricular conduction, growth retardation, and micrognathia, are not often obvious. In summary, triploidy should be suspected in all cases of partial mole when the placenta contains several areas of focal sonolucency representing vesicles or when severe IUGR occurs in the second trimester.
