Brain MRI findings of the patient. (A-C) Brain MRI at 6 months of age on the third day of admission (A, B: T2-weighted image, C: ADC) reveals symmetrical T2 signal prolongation with restricted diffusion in the caudate nucleus, putamen, globus pallidus, medial thalamus, and substantia nigra (white arrow). (D-F) Brain MRI on the 26th day of admission (D, E: T2-weighted image, F: ADC) shows progression of liquid degeneration of the basal ganglia and cerebral atrophy. (G-I) Brain MRI at 1 year and 9 months after onset (G, H: T2-weighted image, I: ADC) shows severe liquid degeneration of the basal ganglia and cerebral atrophy.
