(a) Coronal T1 gadolinium enhanced sequence demonstrating left optic neuritis with enhancement and enlargement of the left optic nerve (arrow). (b) and (c) Axial FLAIR demonstrating typical well-circumscribed ovoid lesions in the juxtacortical and periventricular regions consistent with 2010 McDonald criteria for dissemination in space. (d) and (e) Axial FLAIR and gadolinium enhanced sequences with corresponding asymptomatic enhancing and nonenhancing lesions consistent with 2010 McDonald criteria for dissemination in time. (f) Axial T1 sequence with hypointense lesion associated with acute demyelination and axonal injury.
