Vein of Galen malformation and infantile spasms.

Recently, there has been increasing interest in the study, characterization, and management of infantile spasms. With technological advances, it is now possible to determine a specific diagnosis on many patients with infantile spasms, thus broadening the spectrum of conditions associated with this electroclinical syndrome. We report a child with infantile spasms who also had a vascular malformation of the vein of Galen. Both clinical and electroencephalographic findings improved rapidly after endovascular treatment of the vascular anomaly, suggesting a possible association.
