case_images: In the MR angiography, short signal gap of the left ICA in the proximal vessel segment shortly after carotid bifurcation, but without impairment of the downstream vessel signal.. ICA: internal carotid artery; MR: magnetic resonance.

case_images: Additionally, MRI angiography of intra- and extracranial vessels revealed a short signal void in the proximal segment of the left ICA, post-carotid bifurcation, without impacting downstream vessel signal, indicative of severe stenosis (Figure 1).
case_images: PET-CT scan demonstrating the thoracic aorta with a moderate excess of fluorodeoxyglucose uptake, indicating increased metabolic activity, with only mild atheromatosis present (a and b).. PET-CT: positron emission tomography-computed tomography.
