Figure 1. — A) Axial computed tomography on admission, at the level of the anterior callososeptal interface, showing unremarkable findings. B) Axial FLAIR image showing a typical hyperintense lesion in the callososeptal interface. C) Axial T1-weighted image obtained after gadolinium administration showing slight enhancement of the lesion in the early phase. D) Sagittal FLAIR image showing that the lesion had propagated along the medullary venules and was perpendicular to the lateral ventricles in a triangular configuration (i.e. Dawson's fingers; arrow); another MS lesion of the occipito-mesial juxtacortical white matter was noted as an incidental finding (arrowhead). E) Coronal T1-weighted image obtained after gadolinium administration showing more pronounced enhancement of the lesion in the late phase.
