Panels A (axial DWI), B (axial ADC) and C (axial T2 FLAIR) are brain magnetic resonance
imaging sequences illustrating restricted diffusion compatible with an acute infarct
involving the left globus pallidus, corona radiata, and the body of the left caudate
nucleus. Panel D is a 3D reconstruction image of CT angiography of the chest
illustrating high-grade stenosis of the right subclavian artery with post-stenotic
aneurysmal dilatation.

Emergent brain magnetic resonance imaging showed diffusion restriction within the left basal ganglia, a terminal internal carotid artery (ICA)/M1 occlusion, a large perfusion deficit in the left middle cerebral artery territory, and a chronic right thalamic infarct (Figure 1A-C). Chest CT angiogram demonstrated bilateral C7 cervical ribs with associated high-grade stenoses of the bilateral subclavian arteries, right greater than left (Figure 1D).
