MRI studies at onset (a-c) and 1-month follow-up (d-f). Sagittal FSE-T2 image (a) demonstrating hyperintense regions in the splenium of the corpus callosum (white arrow). DWI (b) image shows its hyperintense signal (black arrow) and ADC map (c) shows its reduced diffusivity. Corresponding sagittal FSE-T2 image (d) and DWI images (e) showing normal signal in the splenium of the corpus callosum (white arrow head and black arrow head, respectively) where the ADC map (f) shows normalization of water diffusivity.

Brain MRI showed an area of high signal on fast-spin-echo (FSE) T2-weighted images and high signal on diffusion weighted imaging (DWI) with a decreased apparent diffusion coefficient (ADC) value of 670 x10-3 mm2/sec, observed with a region of interest size of 19 mm2, in the splenium of the corpus callosum (Figures 1(a)-1(c)). Thirty-day follow-up brain MRI showed resolution of the abnormal callosal finding on both T2-weighted images and DWI-ADC maps (Figures 1(d)-1(f)).
