Reversible MR Findings in Marchiafava-Bignami Disease

Figure 1

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.
