Figure 3 Galen aneurysmal malformations-associated cerebral vascular changes. A: Sagittal T1-weighted magnetic resonance imaging in this adult (Patient 5) with a VGAM shows extensive flow voids within the quadrigeminal cistern and in the medial parietal and occipital lobes; B, C: Catheter cerebral arteriography with internal carotid (B) and vertebral artery (C) injections show that multiple independent arteriovenous fistulas of the sagittal sinus, falx, and tentorium are present; D, E: Post-embolization lateral scout (D) and left vertebral artery angiogram (E) show the coil mass within the venous pouch and near complete obliteration of the lesion.
