Vertigo with a vestibular dysfunction in children during respiratory tract infections

Abstract

Sudden balance disorders with violent vegetative symptoms (nausea and vomiting) pose a diagnostic and therapeutic problem. In children vertigo/ dizziness with symptoms of vestibular dysfunction is rare, but as vascular etiology is unlikely in children such symptoms arouse concern. This article presents two cases of this type of vertigo. The patients were two boys (6 and 9 years old). They came down with similar symptoms: sudden dizziness, disabled walking, nausea and vomiting, spontaneous nystagmus, and a positive Romberg test. The onset of the balance disorder was preceded by respiratory infection: common cold with symptoms of inflammation of the mucous membrane in the nose and throat. Laboratory tests revealed increased levels of C-reactive protein only in the older boy. Neuroinfection and a displacement process were ruled out. Videonystagmography revealed vestibular dysfunction and vestibular neuronitis on the left side.
