Specimens from the cerebellum show a destructive process of great severity, but a little irregular in extent, affecting chiefly the Purkinje cell belt. The Purkinje cells are often absent throughout one side of a given lamina, and there has ensued a dense accumulation of neuroglia cells along a former Purkinje cell belt, together with a considerable gliosis of the molecular layer. Considerable gliosis of the white matter, both diffuse and perivascular in distribution.

Perivascular plasma cell infiltrations as in cerebrum, but largely meningeal or in the white matter.

Sections from the corpora striata demonstrate a mild and early granular ependymitis, considerable subependymal gliosis of cellular type, considerable perivascular gliosis in the white portions of the tissue, and a moderate infiltration of perivascular sheaths with pigmented cells, lymphocytes, and plasma cells. There is little evidence of alteration in the nerve cells. Some are unevenly pigmented.
