Encephalitis periaxialis diffusa

This is the name of the disease, the first 2 cases of which were described by Schieder in 1912-1913. Macroscopically with it, according to Graf (Arch. F. Psych .. Bd. 73), a limited focus is found in the brain of the hemispheres, and histologically - the disintegration of the pulp with the relative intactness of the axial cylinders, rich development of granular and large spider-like cells, increased neuroglia and vascular infiltrates.
