case_images: An urgent head computed tomography (CT) showed no active parenchymal lesions; an angio-CT of the neck vessels and of the intracranial vessels showed reduction of caliber of the right internal carotid artery from its origin and then occlusion of the vessel from the C1-C2 level, involving the extracranial and intracranial tract (Fig. 1).
case_images: a Brain MRI scan (coronal FLAIR sequence) shows a high signal intensity area on the right hemisphere, including also the tongue area of the primary motor cortex (arrow). b Brain MRI scan (axial diffusion-weighted image) shows restricted diffusion with high signal intensity in the same area (arrow).
