[Kufs disease with leukoencephalopathy].
We report a case of adult neuronal ceroid lipofuscinosis (Kufs' disease) with leukoencephalopathy on cerebral scan CT and MRI. A 52 year-old woman presented with partial complex epileptic seizure followed by progressive dementia, cerebellar ataxia, pyramidal and akineto-rigid signs and symptoms. After 6 years of evolution, cerebral stereotactic biopsies showed a diffuse gliosis of the white matter, but no clear demyelination. Nerve and glial cells contained numerous PAS+ autofluorescent granules. In the oligodendrocytes and astrocytes of the white matter these granules appeared electronmicroscopically as cytoplasmic osmiophilic lamellar bodies with fingerprint profile combined with some curvilinear and rectilinear aspects. The cortical nerve cells contained granular osmiophilic bodies. This "leukoencephalopathic" variant of Kufs' disease is probably related to the pigmentary type of orthochromatic leukodystrophy, wherein similar inclusions have been only described in the macrophages and glial cells of the white matter.
