Background And Objectives: Bilateral sequential vestibular neuritis (BSVN) is a rare condition in which an inflammation or an ischemic damage of the vestibular nerve occurs bilaterally in a sequential pattern. We described four cases of BSVN.
Subjects And Methods: Every patient underwent video-head impulse test during the first and the second episode of vestibular neuritis (VN), furthermore they have been studied with radiological imaging.
Results: Contralateral VN occurred after a variable period from prior event. Vestibular function recovered from the first episode in one case. The other three patients developed contralateral VN. One case was due to a bilateral VN in association with a Ramsay-Hunt syndrome, in another patient clinical records strongly suggested an ischemic etiology, whereas in two cases aetiology remained uncertain. Two patients subsequently developed a benign paroxysmal positional vertigo involving the posterior canal on the side of the latest VN (Lindsay-Hemenway syndrome).
Conclusions: Instrumental vestibular assessment represents a pivotal tool to confirm the diagnosis of VN and BSVN.

Previous studies have highlighted the correlation between inflammatory responses and vestibular neuritis (VN). The aim of Mendelian randomization was to assess the causal associations between 91 inflammatory proteins and vestibular neuritis comprehensively. By leveraging publicly accessible genetic datasets, we probed whether 91 inflammatory proteins serve as upstream determinants of vestibular neuritis.

: Skull vibration-induced nystagmus (SVIN) has become a validated tool for evaluating the vestibular function. The presence of SVIN is a useful indicator of the asymmetry of vestibular function between the two ears. In unilateral vestibular loss, a 100 Hz bone-conducted vibration given to either mastoid immediately causes a primarily horizontal nystagmus.

Purpose: Number magnitude is often represented spatially in the mind by a mental number line, on which small numbers are located to the left of space and large numbers to the right. As vestibular dysfunction can affect aspects of spatial cognition, we wondered whether patients with acute vestibular loss would show a directional bias along the mental number line.
Methods: We gave 18 patients with vestibular neuritis (VN) (eight left VN, ten right; mean age 54 years, range 31-75 years; four females) and 15 normal age- and education-matched controls (mean age 47 years, range 26-75 years; 11 females) a mental number bisection task.

Introduction: Venous thromboembolism (VTE) rarely presents with dizziness as the primary complaint, which can delay diagnosis. We report a rare case of dizziness as the chief complaint for a clot-in-transit and extensive bilateral pulmonary emboli.
Case Description: A 70-year-old woman presented to the emergency room (ER) with dizziness and a fall, without reporting loss of consciousness.
