Pallidonigral pigmentation and spheroid formation with multiple striatal lacunar infarcts.

A 72-year-old hypertensive man had focal seizures and mild memory loss. At autopsy, there were many lacunar infarcts, particularly in the neostriatum. Rust-brown discoloration and spheroid formation within the globus pallidus and pars reticulata of the substantia nigra resembled Hallervorden-Spatz disease, in which more detailed analysis of the striatum may be worthwhile.
