Summary The present report documents a family with three cases in two successive generations of pigmentary orthochromatic leukodystrophy (POLD). The clinical features of these cases and histochemical and ultrastructural investigations of two of the brains from successive generations are discussed. A review of the familial cases of POLD reported in the literature is also presented. Transmission of these cases was by a dominant inheritance. Onset of the clinical symptoms occurred at 42 to 54 years of age; duration of the disease was from 2–11 years, and death occurred at 45 to 57 years of age. Clinical manifestations of all three cases were severe headaches; bilateral pyramidal, pseudobulbar, cerebellar, and frontal release signs; gait disturbances; euphoria, or apathy; epileptic seizures; and dementia. The neuropathological pattern consists of slight cerebral atrophy, brownish discoloration of the cerebral white matter with demyelination and severe gliosis, sparing the sub-cortical U fibers; presence in the macrophages of lipid pigment granules that are sudanophilic, non metachromatic, and PAS and iron positive. The electron microscopic pattern of the lipid pigment in the macrophages is that of ceroid: electron-dense, membrane-bound intracytoplasmic lysosomes with curvilinear and/or fingerprint profiles.
