An autopsy case of late infantile and juvenile neuroaxonal dystrophy with diffuse Lewy bodies and neurofibrillary tangles
The clinical and pathological features of a sporadic case of juvenile neuroaxonal dystrophy beginning at the age of 10 and leading to death at the age of 26 are described. Clinical manifestation began with cerebellar symptoms. The subject subsequently developed dementia, pes cavus (Friedreich's feet), epilepsy, myoclonus, and Parkinsonian syndrome, but demonstrated neither tremor nor choreoathetoid movement. Pathological examination showed typical generalized axonal dystrophy throughout the central nervous system (Seitelberger's disease). Iron-positive pigmentation was seen in the pallidonigral system, diffuse Lewy bodies (brainstem type and cerebral type) were demonstrated in the brainstem nuclei and cerebral cortex, and neurofibrillary tangles were observed.
