(A,C) Axial T2-weighted magnetic resonance imaging (MRI) slices showing symmetrical hyperintensity in the globus pallidus at 17 days (A) and 3.5 months (C) after poisoning, demonstrating a reduction in globus pallidus hyperintensity. (B,D) Coronal fluid-attenuated inversion recovery MRI slices at 17 days (B) showing asymmetry of the hippocampus larger on the left side and improved symmetry at 3.5 months (D) after poisoning.

Cerebral magnetic resonance imaging (MRI) showed abnormal signals from bilateral globus pallidus and asymmetry of the hippocampus larger on the left side (Figure 1). MMSE score at that time was 26/30, with short-term memory improved, but the orientation ability to time and place was still impaired. MRI showed that the range of abnormal signals of bilateral globus pallidus was reduced (Figure 1). The symmetry of the hippocampus was also improved in the MRI scan (Figure 1), but MRS still showed NAA/(Cho + Cr) < 0.75.
