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.
我们在此描述了一位患者的病例，其主要症状为间歇性眩晕和“人格解体”，即感觉与自己的身体分离。
本病例研究旨在进一步了解眩晕患者出现人格解体症状时的临床评估。
这是一项病例研究。
对一位出现眩晕并伴有人格解体症状的患者进行了前庭功能测试的回顾性图表审查。
前庭功能测试显示左侧颈部和眼源性前庭诱发肌源性电位缺失，而视频头脉冲试验或视频眼震图、旋转椅检查结果正常，提示左侧囊斑和椭圆囊的外周前庭功能障碍。
耳石器官损伤解释了患者在试图行走时向左侧的姿势偏差。我们建议临床医生应注意患者的人格解体症状，并进行前庭诱发肌源性电位检查，以确定是否存在至少单侧外周耳石器官损伤的证据。
