Figure 40 (A-D): Gray-scale and Doppler coronal USG demonstrating a cystic midline structure in the region of posterior third ventricle with mass effect. (A) Typical swirl effect is noted on Doppler (B). Findings are highly suggestive of aneurysmal malformation of the vein of Galen. The corresponding axial and sagittal T2W images of MR examination confirming large aneurysmal dilatation of the vein of Galen (C and D)
