Right superior caval vein to the left atrium in a child with vein of Galen malformation.

Vein of Galen malformation (VGM) is a rare intracranial vascular malformation. High output heart failure is common in infancy and is characterized by dilatation of all the cardiac chambers. We report an unusual case of VGM in a 3-month-old infant without dilatation of the right-sided cardiac chambers. We then demonstrate importance of comprehensive evaluation in detecting rare coexistence of anomalous right superior caval vein connection to the left atrium.
