Presentation transcript:

A 69-year-old patient with subarachnoid and intraventricular hemorrhage on CT of the head (A). A 69-year-old patient with subarachnoid and intraventricular hemorrhage on CT of the head (A). Left external carotid artery (ECA) injection, anteroposterior (B) and lateral (C) views, showing an aggressive torcular dural arteriovenous fistula (DAVF) with arterial feeders from the middle meningeal artery (MMA), occipital artery and posterior auricular artery and venous drainage into the peritorcular cerebellar cortical veins (single arrow). Superselective distal left MMA injection (D) revealed similar angioarchitectural findings of the fistulous point. Final left ECA lateral angiography (E) showed complete occlusion of the fistula after a single infusion via the left MMA. (Used with permission from Barrow Neurological Institute). Yin C Hu et al.
