case_images: A high signal on diffusion-weighted imaging (DWI) and a reduction in the apparent
  diffusion coefficient in the lateral aspect of the hippocampus (a and b).
  Fluid-attenuated inversion recovery (FLAIR) showed no change in the hippocampus (c).

case_images: fig1-2050313X211054644
case_images: Initial MRI with DWI revealed abnormal signals in the hippocampus with a slightly decreased apparent diffusion coefficient, and no change was seen in the hippocampus with fluid-attenuated inversion recovery (FLAIR) (Figure 1(a)-(c)).
case_images: An intense high signal on DWI in both axial and coronal views in the lateral aspect of
  the hippocampus (a and b). FLAIR showed a high signal in the hippocampus (c).

case_images: fig2-2050313X211054644
case_images: Repeat MRI with DWI on Hospital Day 4 revealed hyperintense signals predominantly in the hippocampus with hyperintense signals on FLAIR in the same location (Figure 2(a)-(c)).
case_images: Shows almost no signal changes in the hippocampus on DWI and FLAIR (a and b).

case_images: fig3-2050313X211054644
case_images: The third MRI with DWI and FLAIR showed a very mild signal change in the hippocampus on Hospital Day 13 (Figure 3(a) and (b)).
