Brain magnetic resonance imaging (day 6) showing possible cerebral vasculitis in multiple axial sequences. *Punctiform hyperintensities in diffusion-weighted imaging (a) in several vascular territories with cortical and sub-cortical distribution. These lesions appear with a normal or decreased axial apparent diffusion coefficient value (b) and some are enhanced after gadolinium injection in T1 sequences suggesting a blood-brain barrier disruption (c) and consistent with semi-recent ischemic lesions. **Ependidymal enhancement in T1 with gadolinium enhancement sequences, sign of ventriculitis (c)
