A Case of Multiple Sclerosis in which Vertigo was the Chief Complaint

Multiple sclerosis patients sometimes complain of vertigo as one of their symptoms. We experienced a case in which vertigo was seen as the chief complaint. MRI and neurootological examinations led to the diagnosis that the vertigo was caused by recurrent multiple sclerosis lesions of the posterior cranial fossa. We then considered five earlier multiple sclerosis patients who had vertigo. Their pure tone audiogram and caloric tests were almost normal. However, neurootological examinations ETT, OKP and gravicorder showed abnormalities. Therefore, in addition to MRI T2 and T2 FLAIR image examinations, neurootological examinations are valuable for diagnosis, especially in order to detect posterior cranial fossa lesions.
