Enlargement of the vein of Galen
It is the consequence of two types of arteriovenous malformation: the vein of Galen aneurysmal malformation and the pial arteriovenous malformation. The sonographic appearance is similar and the most prominent finding is the enlargement of the vein of Galen, that on Color Doppler contains turbulent blood flow.
