Brain magnetic resonance imaging (MRI) at the initial presentation and after two months. Brain MRI five days after admission (A-D) shows a FLAIR-weighted image with non-active MS typical lesions (B), a diffusion-weighted image illustrating multiple dot-shaped cortical and subcortical lesions with restricted diffusion not limited to a large-vessel vascular territory and corresponding reduction on the apparent diffusion coefficient sequence (B,C), a contrast enhanced T1-weighted image without any intracerebral contrast enhancement (D; circular contrast uptake of the cerebral meninges due to a previous lumbar puncture). The follow-up MRI after two months (E-F) shows a diffusion-weighted image without any new lesions (E) and a contrast enhanced T1-weighted image with dot-shaped contrast-enhancing lesions (F) in contrast to the initial presentation.
