The comparison of imaging findings at different times. A Images of T2 weighted imaging (T2WI) (the top row) and diffusion-weighted imaging (DWI) (the bottom row) in the local hospital at different times (2 days, 27 days, and 3 months after onset, respectively) showed symmetrical hyperintensity of bilateral basal ganglia nuclei. B Comparison of MRI imaging at different sequences in our hospital, including T2WI, T2-fluid attenuated inversion recovery (FLAIR), DWI, apparent diffusion coefficient (ADC), susceptibility-weighted imaging (SWI) sequences, and magnetic resonance spectrum (MRS), respectively. The radiologic findings showed hyperintensity of the bilateral caudate head and putamen in T2WI, FLAIR, and DWI, which were associated with scattered hypointensity in ADC and SWI. MRS showed decreased NAA in bilateral putamens with the emergence of a lipid peak in the left side
