title: Glycogen accumulation in the central nervous system in the cerebro-hepato-renal syndrome. Report of a case with ultrastructural studies.
abstract: We found marked accumulation of glycogen in the brain in one case of the cerebro-hepato-renal syndrome (CHRS). Glycogen in the form of beta-particles was deposited freely within the nucleus, perikaryon and cell processes of neurons and glial cells. The changes involved the gray matter diffusely but were more prominent in the cerebral cortex. The patient died at the age of 4 months after a clinical course characterized by severe hypotonia, seizures, and apneic episodes. Other neuropathologic findings were developmental malformations of the central nervous systen (CNS) (pachygyria, polymicrogyria, and hypoplasia of the inferior olives), white matter abnormalities (deficiency in myelination and diffuse accumulation of sudanophilic droplets within glial cells), clusters of peculiar "globoid" histiocytes with pleomorphic lipid inclusions, and microglial nodules in gray and white matter. This unusual combination of findings is regarded as characteristic of the CHRS.
