case_images: Serial patient's brain MRIs are shown in the picture. Respectively, T2-FLAIR (first two pictures), DWI, and ADC sequences are reported. In the first MRI (a), a cortical-subcortical left frontal lesion, involving the cingulate gyrus, and an ipsilateral paramedian, parietal cortical lesion are evident. Both lesions are hyperintense on T2, T2-FLAIR, and DWI sequences, while ADC is mildly decreased. No lesions were detected in the basal ganglia on T1, T2-FLAIR, DWI, and ADC sequences (b). After 6 days (c), the left parietal T2-FLAIR hyperintensity was clearly reduced, while the frontal one was just slightly diminished. DWI restrictions in both areas were decreased, especially in the parietal location. ADC was normal. T1 sequences were slightly hypointense. The follow-up MRI imaging at 4 months (d) showed complete regression of the abnormalities.

case_images: DWI hyperintensity in both areas was markedly reduced (shown in Fig. 1).

case_images: Eventually, 15 days after the admission, the patient was discharged to a rehabilitation facility, where the choreic-hemiballistic involuntary movements completely subsided within 20 days after their onset, in parallel with the improvement of the patient's glycemic control (shown in Fig. 2).
