Vein of Galen Aneurysmal Malformation: Antenatal Diagnosis by Ultrasound and MRI

Abstract

Vein of Galen aneurysmal malformation is a rare intracranial arteriovenous malformation .It accounts for up to 30% of intracranial vascular malformations in pediatric population and 1% of all pediatric congenital anomalies. It causes severe morbidity and mortality in neonates in the form of high output cardiac failure, nonimmune hydrops, hydrocephalus and intracranial hemorrhage. It is often diagnosed in postnatal period. Prenatal diagnosis of VGAMs may be accomplished with prenatal ultrasound (US) and fetal MRI which helps in early diagnosis and effective management.
