Audiovestibular Correlates in an Individual with a Retrocerebellar Arachnoid Cyst

Abstract

Abstract The central vestibular lesion is mainly responsible for vertigo without nausea and may manifest with localized neurological symptoms such as diplopia, ataxia, and decreased cranial nerve function. This case study focuses on detailed audiological and vestibular assessment procedures patient with unidentified and later identified with arachnoid cysts in the retrocerebellar region. A 40-year-old female presented with a complaint of giddiness and instability, with each episode of giddiness lasting up to 10–15 min with unconsciousness. The results of the audiological evaluation indicated bilateral moderate sensorineural hearing loss, with an “Add” type tympanogram in both the ears. The findings of vestibular evaluation suggested of positive central vestibular lesion. This case report emphasizes differential diagnosis between peripheral and central vestibular lesions and requires detailed analysis and correlation of audiological and neurological symptoms. We recommend to use HINTS or HINTS+, which can help in episode of acute vertigo.
