Vein of Galen malformation

Case contributed by Assoc Prof Frank Gaillard

CTA brain

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)


Transcranial Ultrasound

Doppler examination on the left and the same level grey scale image demonstrates the aneurysmally dilated VOG.


MRI Brain

Axial T2 weighted images demonstrates the aneurysmally dilated vein of Galen. 

Case Discussion

Features are consistent with a vein of Galen malformation.
