Pigmentary type of orthochromatic leukodystrophy with early onset and protracted course.
The pigmentary type of orthochromatic leukodystrophy (OLD) is a rare disorder in adults; only one questionable childhood case has been observed. We report the sporadic case of a male aged 26 years with early onset and protracted course. He presented retarded motor development from birth with ataxic gait and, at age 13 years, developed progressive mental and neurologic deterioration with tetraparesis, ataxia and seizures and died in a disabled, mute state. Repeated CT scans showed progressive diffuse cerebral atrophy and low density of the hemispheric white matter. Autopsy revealed OLD with pigmented macrophages and glial cells, ultrastructurally showing storage of lipofuscin and ceroid with multilamellar bodies or finger-print profiles. Abnormal cytoplasmic inclusions in reduced oligodendroglial cells suggest demyelination due to a primary defect of oligodendroglia in this rare disorder.
