Computed tomography angiogram of the head and neck obtained five hours after the injury. The image shows a pellet wedged in the lumen of the right internal carotid artery approximately 2 cm above the bifurcation (at the C2/C3 level), and a filling defect in the right middle cerebral and right internal carotid arteries distal to the pellet (right).

Computed tomography (CT) angiography of the head and neck showed the pellet in the lumen of the right internal carotid artery (ICA) 2 cm above the bifurcation (at the C2/3 level) with a distal filling defect and developing ischaemia in the middle cerebral artery territory (Fig. 1).
Angiography of the neck and head. Anteroposterior (left) and lateral (right) views showing the pellet in the right internal carotid artery approximately 2 cm above the bifurcation. The internal carotid artery is completely occluded, only external carotid artery branches are displayed.
