Multiple system atrophy with retinal degeneration in a young child.Neuropediatrics 1987; 18(2):91-5N
A 4-year-old girl with multiple system degeneration and retinal degeneration was presented. There was onset of an ataxic gait at two years and rapid progression of retinal degeneration, myoclonus and cranial nerve palsy. Neuropathological examination revealed severe degeneration of the cerebellar cortex and the pathways of auditory and deep sensation, as well as degeneration of the cerebellar efferent fibers, the striatonigral system, the cerebellar afferent fiber system and lower motor neurons. Cases of young children with spinocerebellar degeneration have been reported in several families of olivopontocerebellar atrophy (OPCA), but degenerative changes in our case were more widespread than those in OPCA cases. The multiple system lesions in the central nervous system and retina of this child are different from those of any other previously reported cases.
