title: [Cavitating neutral fat leukodystrophy with recurrent course].
abstract: A girl with non-contributory family history, at the age of 7 years developed a recurrent ataxic-spastic syndrome followed by disorders of consciousness and seizures. She died in a decerebrate state at the age of 10 9/12 years. Diffuse EEG abnormalities changed in accordance with the clinical course. CSF findings were always negative. Brain biopsy performed at the age of 9 5/12 years was non-diagnostic. No clinical signs of adrenal insufficiency were present. Neuropathological examination disclosed severe demyelination of the cerebral white matter with formation of large periventricular cavities, relative sparing of the subcortical arcuate fibers, and peripheral myelin breakdown of the orthochromatic (neutral fat) type. There was complete absence of inflammatory lesions, comparative preservation of axons and oligodendroglia with moderate astroglial reaction. The optic system and cerebellum were not involved. Additional postanoxic changes were seen in the thalamus and hippocampus. The sporadic case is suggested to represent a cavitating form of neutral fat (simple orthochromatic) leukodystrophy which is to be separated from Schilder's diffuse sclerosis and adrenoleukodystrophy. The etiology of the disorder is unknown.
