[Findings of computed tomography in the acute form of Marchiafava-Bignami disease].

We report a case of Marchiafava-Bignami's disease with acute evolution. Pathological examination was carried out and a cavitary lesion with discontinuous longitudinal extension was found throughout the corpus callosum. CT had shown a narrow hypodense area symmetrically localized just anterior to the frontal horns of the lateral ventricles, corresponding to the genus of the corpus callosum. The literature is reviewed, the anatomical-radiological correlations are discussed, and the possibility of the diagnosis of this condition during life is commented.
