From the case:
Arteriovenous malformation - cerebral
Axial T2

T2 axial imaging demonstrates numerous serpiginous flow-voids consistent with a very large right-sided arteriovenous malformation (AVM).
From the case:
Arteriovenous malformation - cerebral
Frontal Internal carotid artery

Angiography demonstrates arterial supply from both internal carotid arteries and posterior circulation (only left ICA injection shown).
Case Discussion
Typical appearances of a large cerebral AVM.
