case_images: (A-F) Axial brain magnetic resonance imaging (MRI) of the patient showed bilateral symmetrical hyperintensities in the dorsal pontine base (red arrows) and thalamus (yellow arrows) on day 5 of hospitalization (A and B, T2-fluid-attenuated inversion recovery [FLAIR]; C and D, diffusion-weighted imaging; and E and F, apparent diffusion coefficient maps). (G-L) MRI signal changes in the pons and thalamus improved on day 12 of hospitalization (G and H, T2-FLAIR; I and J, diffusion-weighted imaging; and K and L, apparent diffusion coefficient maps).

case_images: T2-fluid-attenuated inversion recovery (FLAIR) hyperintensities in the dorsal pontine base and thalamus (Figure 1A and 1B). The lesions showed high signal at diffusion-weighted imaging and apparent diffusion coefficient maps, indicating T2-shine through (Figure 1C, 1D, 1E and 1F). After five rounds of plasma exchange and levetiracetam administration, she remained seizure-free and MRI signal changes improved (Figure 1G, 1H, 1I, 1J, 1K and 1L).
