Several cases had occasional perivascular mononuclear cell aggregates, in both gray and white matter. Shown are examples from BSHRI Case B4, a male in his 80s(A), Case B2, a female in her 70s (B), Case B6, a male in his 70s (C), Case B8, a male in his 80s(D), and Case B9, a male in his 70s (E). Also shown is a microglial nodule in the posterior medulla in the region of the nucleus gracilis, in BSHRI Case B6 (F). Images are from H & E-stained 80 μm thick sections (B-E) or 6 μm paraffin sections (A, F).
