- Fig 1.
DSA of the left internal carotid artery, lateral view. There is an abnormal blush within the apex of the left orbit (O) and a left intracerebral (I) AVM extending posteriorly along the left optic nerve, tract, and radiations. This is fed by distal branches from the left internal carotid artery, as well as the anterior cerebral artery, a prominent anterior choroidal artery, and thalamic perforators from the posterior communicating artery, not demonstrated in the current view.

Lateral view of a left vertebral artery injection (V) showing the same left intracerebral AVM (A), as seen in Fig 1, fed by thalamic perforators arising from the left posterior communicating artery.
- Fig 3.
DSA of the right external carotid artery injection.
A, Early arterial phase, lateral view, showing 2 nodular areas of abnormal blush fed by prominent arterial branches in the thyroid gland.
B, Oblique view, midarterial phase, showing increase in prominence of the thyroid gland arteriovenous malformation and early draining veins (not shown here). These findings are consistent with multiple high-flow vascular malformations.
