MR imaging of patient 1 on day 4 (A and B), day 6 (C−E), and day 65 (F). A and B, Axial diffusion-weighted image on day 4 (A) shows a high-signal-intensity lesion in the splenium of the corpus callosum with mild high signal intensity on the T2-weighted image (B). C, The splenial diffusion abnormality has disappeared on day 6. D, Diffusion-weighted image on day 6 shows abnormally reduced diffusion in the bilateral middle cerebellar peduncles and cerebellar nuclei. E, T2-weighted image shows mild hyperintensity in the cerebellar cortex, in addition to the middle cerebellar peduncle and nuclear lesions seen in D. F, MR imaging on day 65 shows an almost normal cerebellum other than mild atrophy.

MR imaging of patient 2 on days 6 (A and B) and 13 (C and D) and 1 month (E). A and B, Axial diffusion-weighted images on day 6 show reduced diffusion in the splenium of the corpus callosum with a normal-appearing cerebellum. C and D, FLAIR image on day 13 shows no splenial lesion, but high signal intensity in the cerebellar cortex (arrow). E, FLAIR image through the cerebellum at 1 month shows the development of atrophy.
