まれな小児の前庭神経炎例

This paper deals with the findings obtained in a 9-year-old girl with vertigo who was diagnosed as having classical vestibular neuronitis. The case provided evidence that classical vestibular neuronitis could occur in children under 10 years with the symptom of vertigo.
She had neither remarkable subjective symptoms nor deviation of the extremities at 4 days after the onset. It appeared that vestibular neuronitis in young children recovered faster than in older cases who have more chances of being examined. At first visit (4 days after the onset) rotato-horizontal nystagmus to the intact side was remarkable. The nystagmus became less remarkable with time until it disappeared one month and a half after the onset. The caloric test revealed advanced CP (canal pareais). The patient under the discussion did not recover from this disorder throughout the observation period. The vestibular neuronitis findings obtained in a 9-year-old girl with vertigo were identical to those obtained in older people.
