MRI non-contrast venography confirmed the presence of an abnormal venous structure draining into the vein of Galen (A, B, white arrows). Digitally subtracted angiography (venous phase) confirmed the MRI finding suggesting a DVA of the mesencephalon running posteriorly with a prominent drainage to the vein of Galen (C, D, white arrows). There was no diffuse capillary stain, abnormal venous disposition or arterial-venous shunting observed of the selective angiography from the left internal carotid artery.
