(a) A DAVF in the left transverse-sigmoid sinus was shown on the arterial phase of the left common carotid artery angiogram (anteroposterior view). (b) Numerous draining cortical veins of the AVF indicating severe venous reflux and congestion were demonstrated on the venous phase of the angiogram (anteroposterior view). (c) On the arterial phase of the lateral view, a DAVF had many feeding arteries, meningeal branches from the external carotid artery, cortical venous reflux, and the isolated left transverse-sigmoid sinus as drainer. (d) Note the cortical venous congestion in the wide area of the left cerebral hemisphere.

Its feeding arteries were the left occipital artery, posterior auricular artery, middle meningeal artery, and superficial temporal artery (Figure 1).
In a former axial image of 3D-CT angiography arterial phase obtained after admission, abnormal vessels (circle markings) appeared in the left cerebral hemisphere including the DLPFC (arrow).

In a former axial image of 3D-CT angiography arterial phase obtained after admission, abnormal vessels appeared in the left cerebral hemisphere including the left dorsolateral prefrontal cortex (DLPFC) (Figure 2).
A DAVF disappeared on the angiograms (a) anteroposterior view and (b) lateral view.
