Brain MRI, performed at 6 weeks after the onset of the last stroke, showed the two lesions: a subacute ischemic lesion in the territory of the right lenticulostriate artery (involving the caudate head, putamen and part of the pallidum), and an ancient lesion in the territory of the left lenticulostriate artery (involving the caudate head and the surrounding white matter with the ipsilateral frontal horn enlargement) (fig. 1).
