CTA of the brain of an infant (images 1, 4 and 5) demonstrates marked dilatation of a vessel in the region of the vein of Galen with multiple enlarged feeding arteries from both sides. Drainage is via both a persistent falcine sinus and the straight sinus. (Note it is not actually the vein of Galen, but rather a persistent median prosencephalic vein)

Axial T2 weighted images demonstrates the aneurysmally dilated vein of Galen.
Case Discussion
Features are consistent with a vein of Galen malformation.
