MRI (27.04) T2 dark fluid sequence, sagittal projection. Presence of ring-line high-signal foci with perifocal polydigital changes as a manifestation of a perifocal edema, situated in the pons, medulla oblongata, cerebellar vermis and frontally in the juxta-cortical region. The presented localization can be associated with pyramidal and motor coordination symptoms.

Figs. 1, 2A, 2B and 3 show some of the most pronounced pathological lesions.
A. MRI (27.04.) T2 - TSE sequence, axial projection: ring-like high-signal changes are visualized. These are situated asymmetrically from both sides in the basal nuclei. B. MRI (27.04.) T2 dark fluid, axial sequence. The same level is examined with the presented findings which possess the characteristics of a perifocal and periventricular edema. The high-signal changes bilaterally in the periventricular region are more distinct around the posterior horns of the lateral ventricles.

MRI (16.05) on the T2 weighted sagittal sequence, the fluid is dark. The follow-up MRI shows significant progression of the changes in the meningeal membranes and intra parenchymal in the white brain matter and the periventricular spaces.
