case_images: FIG1
case_images: A head and neck computed tomography with an angiogram (CTA) was performed, showing no brain infarction but a focal occlusion at the left medial cerebral artery in M2-M3 (Figure 1), as well as atheromatous irregularities at the carotid bifurcation with no critical stenosis.

case_images: FIG2
case_images: The head computed tomography (CT) was reviewed, showing small subcortical hypodensities, suggestive of chronic ischemia (Figure 2).
case_images: Computed tomography with angiogram showing subclavian stenosis before and after vascular intervention. (A) Before, orange arrow indicating left subclavian stenosis. (B) After, blue arrow indicating vascular conduit in the left subclavian artery origin.

case_images: A neck and chest CTA revealed diffuse atherosclerotic disease, purely calcified or mixed component, involving: 1. thoracic artery; 2. aortic arch; 3. supra-aortic trunks; 3. brachiocephalic trunk origin; 4. coronary arteries; 5. left main carotid artery origin (50%-60%); 6. left subclavian artery with significant stenosis (Figure 3A). Further ahead, due to persistent symptoms of cooling and paraesthesia in her left hand, she was submitted to percutaneous revascularization with stenting of the left subclavian artery (Figure 3B).
