Figure 2.

The cerebral MRI features of case 8. a, b, and c were conducted seven days after the onset of his symptoms. d and h were taken 15 days after the onset of symptoms. e, f, and g were taken 33 days after the onset of his symptoms. MR demonstrated an isolated oval lesion in the splenium of the corpus callosum (arrows) with hypointensity on ADC (c), hyperintensity on T2 (a), and DWI (b). All abnormal signals disappeared upon a repeat of MR imaging (e: T2, f: DWI, g: ADC). No FA change was observed on DTI; no microbleeding was seen on SWI. ADC: apparent diffusion coefficient, DWI: diffusion-weighted images, FA: fractionary anisotropy, DTI: diffusion tensor imaging, SWI: susceptibility weighted imaging
