Dural AV Malformation / Fistula MRI

MRI Brain Axial FLAIR and coronal T2w images show an extra axial nodular T2 flow voids in right parasellar region, flow related signals on 3D TOF Noncontrast MR Angiography suggestive of a high flow vascular malformation. No direct communication with adjacent right ICA rules out ICA Aneurysm.
It seems to be a Dural Arterio Venous Malformation / Fistula, finding is noted incidentally as pt actually presented for a recent infarct involving cranial portion of right cerebellar hemisphere in superior cerebellar artery territory.
