Abstract：
We describe herein the case of a patient whose primary complaints were episodic vertigo and \"depersonalization,\" a sensation of detachment from his own body.
This case study aims to further clinical knowledge and insight into the clinical evaluation of vertiginous patients with complaints of depersonalization.
This is a case study.
A retrospective chart review of vestibular function testing done on a vertiginous patient with complaints of depersonalization was performed.
Vestibular function testing revealed absent cervical and ocular vestibular evoked myogenic potentials on the left side with normal vHIT or video Head Impulse Test, videonystagmography, and rotational chair results, suggesting peripheral vestibular impairment isolated to the left saccule and utricle.
The otolith end organ impairment explains the patient\'s postural deviation to the left side during attempts to ambulate. We recommend that clinicians should be attentive to patient complaints of depersonalization and perform vestibular evoked myogenic potential testing to determine whether evidence of at least a unilateral peripheral otolith end organ impairment exists.

摘要：
我们在此描述了一个主要主诉为发作性眩晕和“去人格化”的患者的病例，“一种脱离自己身体的感觉。
本案例研究旨在进一步了解临床知识，并深入了解患有人格解体的眩晕患者的临床评估。
这是一个案例研究。
对一名有去人格化主诉的眩晕患者进行前庭功能测试的回顾性图表回顾。
前庭功能测试显示左侧颈部和眼部前庭诱发的肌源性电位缺失，vHIT或视频头部冲动测试正常，视频眼震描记术,和旋转椅子的结果，提示左囊囊和外囊周围前庭损伤。
耳石末端器官受损解释了患者在尝试走动时姿势向左侧偏离。我们建议临床医生应注意患者对人格解体的抱怨，并进行前庭诱发的肌源性电位测试，以确定是否存在至少单侧外周耳石末端器官损害的证据。
