位置性眩晕和眼球震颤可能是由于管结石，壶腹结石，以及不太常见的潜在的外周或中枢前庭疾病。我们报告一位前庭神经鞘瘤的病人，最初是因为体位性眩晕而寻求治疗。滚动试验的视频眼电图显示方向改变的水平向远地性眼球震颤，与水平穹窿结石一致。然而，进一步的听觉前庭检查和影像学检查证实了右前庭神经神经鞘瘤引起的右前庭病变。本病例报告提示前庭神经鞘瘤应被视为另一个潜在的模仿水平壶腹结石。(C)2013爱思唯尔有限公司保留所有权利。
Positional vertigo and nystagmus can be due to canalithiasis, cupulolithiasis and less commonly, an underlying peripheral or central vestibular disorder. We present a patient with vestibular schwannoma who initially sought treatment for positioning vertigo. Video-oculography on the roll-test revealed direction-changing horizontal apogeotropic nystagmus, consistent with horizontal cupulolithiasis. However, further audio-vestibular investigations and imaging confirmed a right vestibulopathy attributable to a schwannoma of the right vestibular nerve. This case report suggests that vestibular schwannoma should be considered as another potential mimicker of horizontal cupulolithiasis. (C) 2013 Elsevier Ltd. All rights reserved.
