Summary

A female, 5-year-old American Staffordshire Terrier with severe progressive neurological deficits, particularly in terms of ataxia and keeping balance, was examined pathomorphologically and a genetic analysis was performed. In neurons of various localizations of the central nervous system an accumulation of a finely granular pale eosinophilic or light brown material was found. In addition, the cerebellum revealed marked degeneration and loss of Purkinje and inner granule cells. The accumulated PAS-positive, argyrophilic, autofluorescent material showed ultrastructurally a lamellar appearance suggestive of lipofuscin. Genetic analysis revealed the presence of a sequence variant in the ARSG gene encoding the lysosomal enzyme arylsulfatase G. This case report describes an adult-onset of a neuronal ceroid lipofuscinosis that shows similarities with a human disorder termed Kufs disease.
