Axial MRI. MRI findings from initial presentation (A-C, D-F). MRI findings of FLAIR (A, D), T1-weighted image with Gd enhancement (B, E) and T2w weighted spinal MRI (C, F). Initial MRI of the brain (A, B) revealed subtle signs of meningitis, MRI of the spinal cord (C) showed no pathological findings. MRI of the brain after admission to ICU (D, E) revealed cortical and subcortical lesions bihemispherically with parieto-occipital emphasis as well as hyperintense signal alterations of the mesial temporal lobes. MRI of the spinal cord (F) revealed expanded oedema of medulla oblongata. (Marked with yellow arrows)
