- Abstract
- We have had an opportunity to study a patient with acute sensory neuronopathy. The patient was a 32-yearold housewife; the rapidly spreaded tingling sensation along both arms and legs developed, rendering her severely ataxic. There was no history of antecedent illness, familial neurological disease, or exposure to toxins and special drugs. On examinations, there was no abnormality in her mental and cranial nerve function. There was no motor weakness. She showed the profound loss of kinesthetic sense which was acutely progressive and associated with severe sensory ataxia and pseudoathetosis. All tendon reflexes were absent.
However, cutaneous senses were preserved. There was no significant abnormal
laboratory finding except elevated CSF protein content. On electrophysiologic findings,
the decrease in the amplitude of action potentials with only mild slowing of conduction
velocities of sensory nerves were found even though motor nerve conduction studies
were normal. Median and tibial somatosensory evoked potentials could be elicited,
although the median N19 scalp response and tibial N45 waveforms were prolonged in
latency. Plasmapheresis were provided; clinical features improved. However, the
electrophy-siological abnormalites remained. Thus we wish to report an additional case
of woman suffering from the acute sensory neuronopathy, complementing the cases
described by Stemm, Schaumburg and Asbury.
