Bilateral sequential vestibular neuritis is a rare condition reported in literature involving the vestibular nerve sequentially. Nowadays, the video head impulse test (vHIT) and vestibular-evoked myogenic potentials provide specific patterns of reduced vestibulo-ocular reflex (VOR) that allow differentiation between complete and partial nerve involvement....
This single case adds limited practice-changing evidence; however, it reinforces that bilateral sequential vestibular neuritis exists and that a combined vHIT and VEMP battery is appropriate when evaluating unexplained bilateral vestibular loss.
Bilateral idiopathic sequential vestibular neuritis is exceptionally rare, and this case contributes to the sparse literature guiding diagnosis and distinguishing it from other causes of bilateral vestibular loss.
- 01Rare case of bilateral idiopathic sequential vestibular neuritis documented with full diagnostic workup.
- 02vHIT and VEMP were key diagnostic tools used to characterize the bilateral vestibular deficit.
- 03Idiopathic etiology means no identifiable cause was found, making diagnosis primarily exclusionary.
- 04Literature review component synthesizes the limited prior published cases.
- 05Published peer-reviewed (DOI: 10.65717/iao.2026.251819).
Bilateral idiopathic sequential vestibular neuritis can be diagnosed using a combination of vHIT and VEMP testing.
