A vein of Galen aneurysmal malformation represents an arteriovenous fistula draining in a dilated precursor of the vein of Galen. We report a case of an incidentally detected large aneurysmal malformation of the vein of Galen in a 25-year-old man. ⋯ This patient had no neurological complaints but the angiography showed, however, a steal phenomenon from the anterior circulation. The lesion was treated with good results by means of endovascular embolization with coils.
