Vein of Galen malformation

Discussion:

Antenatal ultrasound at 32 weeks gestation demonstrates an elongated, anechoic midline structure which extends posteriorly toward the occiput. There is turbulent, low resistance flow on color Doppler.  The features are in keeping with a vein of Galen malformation.

There were no features of fetal hydrops in this case, however this is the major complication that is looked fo in the follow up of such patients.
