Fig 1. Patient 1. Axial fluid-attenuated inversion recovery (FLAIR) imaging (A), diffusion-weighted imaging (DWI) (B), and apparent diffusion coefficient (ADC) mapping (C) performed on admission show T2 prolongation in the medial temporal lobes with reduced diffusion on the right. Follow-up FLAIR images obtained at approximately 5 weeks (D) and 8 weeks (E) after admission show persistent T2 prolongation in the medial temporal lobes and mild volume loss more pronounced in the medial temporal lobes.
