Legend AP and lateral views from a right internal carotid artery angiogram demonstrates a small vascular nidus fed by branches from the middle cerebral artery with an early draining vein from the nidus to the transverse sinus.

Legend The top left image is a pretreatment angiogram performed through a microcatheter which is in the feeding vessel to the AVM nidus. The bottom images were performed following embolization with PVA particles and shows obliteration of the vascular nidus and the early draining vein. Key words: mri angiography vascular
