Vein of Galen Malformation

A vein of Galen malformation is an arteriovenous fistula connecting one or more cerebral arteries and the vein of Galen. Typical patient presentation is high output congestive heart failure. Imaging demonstrates a large mass in the region of the posterior third ventricle that displays vascular characteristics. There is often associated hydrocephalus. Treatment is typically arterial embolization.
