Case 1: (A) axial FLAIR image and (B) axial T2 weighted image, showing ischemic lesion involving the left lentiform nucleus and posterior limb of the internal capsule. (C) Axial FLAIR image and (D) axial T2 weighted image showing resolution of the left lentiform nucleus lesion and reduction of the posterior limb involvement in the internal capsule.

Brain MRI (Figures 1A,B) revealed ischemic lesions involving the left lentiform nucleus and the posterior limb of internal capsule. Four months later, brain MRI showed resolution of the lesion in the left lentiform nucleus and a reduction of the lesion in the posterior limb of the internal capsule (Figures 1C,D).

Case 2: (A) axial T1 image and (B) axial T2 weighted image, showing right thalamic nucleus and posterior limb of the internal capsule ischemic lesions. (C) Axial T2 weighted image and (D) axial T1 weighted image showing resolution of the right thalamic nucleus lesion and reduction of the involvement of the posterior limb of the internal capsule.

MRI revealed ischemic lesions in the right thalamic nucleus and the posterior limb of internal capsule (Figures 2A,B). Magnetic resonance angiography (MRA) showed a reduced caliber of right internal carotid artery, especially evident in the supra-clinoid segment, and of the M1 segment of the middle cerebral artery, hypoplasia of the right A1 segment anterior cerebral artery and tortuosity of the vertebrobasilar system (Figure 3). Five months later, a brain MRI (Figures 2C,D) showed resolution of the lesion in the right thalamic nucleus and a reduction of the posterior limb of internal capsule involvement.
