FIG1
A CT angiography of the supra-aortic and cerebral trunks in the sagittal (Figure 1) and axial (Figure 2) planes was performed, showing an image compatible with arterial dissection, specifically an occlusion of the right internal carotid artery at the cervico-petrous transition by dissection of the cervical segment.

FIG2
A CT angiography of the supra-aortic and cerebral trunks in the sagittal (Figure 1) and axial (Figure 2) planes was performed, showing an image compatible with arterial dissection, specifically an occlusion of the right internal carotid artery at the cervico-petrous transition by dissection of the cervical segment.
