Abstract: | The clinical diagnosis of Marchiafava-Bignami disease (MBD) can be difficult. Acute demyelination of the corpus callosum is characteristic of the disease. The authors report the use of MR diffusion-weighted imaging (DWI) in six cases of acute MBD. They show that apparent diffusion coefficient restriction of the corpus callosum and cortical lesions were associated with a higher mortality rate and more severe cognitive sequelae. |
