Vertigo induced by exposure to the magnetic field of a magnetic resonance imaging (MRI) scanner is a well-known phenomenon within the radiology community but is not widely appreciated by other clinical specialists. Here, we describe a case of an anesthetist experiencing acute vertigo while providing sedation to a patient undergoing a 3 Tesla MRI scan. After discussing previous reports, and the evidence surrounding MRI-induced vertigo, we review potential etiologies that include the effects of both static and time-varying magnetic fields on the vestibular apparatus. We conclude our review by discussing the occupational standards that exist for MRI exposure and methods to minimize the risks of MRI-induced vertigo for clinicians working in the MRI environment.

C-reactive protein-to-albumin ratio and systemic immune-inflammatory index as potential markers in distinguishing acute cerebellar infarction from benign paroxysmal positional vertigo.
Neurosciences (Riyadh)
January 2025
From the Department of Neurology, Faculty of Medicine, Aksaray University, Aksaray, Türkiye.
Objectives: To investigate the potential utility of the C-reactive protein-to-albumin ratio (CAR) and the systemic immune-inflammatory index (SII) as a biomarker in distinguishing between BPPV and acute cerebellar infarction (ACI) due to posterior inferior cerebellar artery (PICA) involvement.
Methods: The data of 2545 patients registered in our hospital database between 2017 and 2024 with a diagnosis of vertigo were retrospectively analyzed and 102 patients with benign paroxysmal positional vertigo (BPPV) and 100 patients with ACI were included in the study. Mann-Whitney U test, Chi-square test, or Fisher's exact test were used to compare variables between the two groups.
Selective otolithic dysfunction in patients presenting with acute spontaneous vertigo: consideration based on MRI.
Front Neurol
December 2024
Dizziness Center, Clinical Neuroscience Center, Seoul National University Bundang Hospital, Seongnam, Republic of Korea.
Objective: Acute unilateral peripheral vestibulopathy or vestibular neuritis (AUPV/VN) manifests as acute onset vertigo, often accompanied by nausea, vomiting, and moderate gait instability. It is suspected when vestibular hypofunction is documented on video-head impulse (video-HITs) and caloric tests in the presence of contralesionally beating horizontal-torsional nystagmus. Herein, we report patients presenting with acute vestibular syndrome (AVS) showing selective otolithic dysfunction in the presence of normal caloric and video-HITs and abnormal enhancement of the peripheral vestibular structures on MRI.

B.P. Koirala Institute of Health Sciences, Dharan, Nepal.
Background: Intra-aural tick infestations, though uncommon, pose a serious clinical challenge owing to the risk of acute labyrinthitis-an inflammatory condition of the inner ear. This inflammation can lead to severe complications such as sensorineural hearing loss, vertigo, and facial nerve palsy. Prompt recognition and management are crucial to prevent these adverse outcomes.

Front Neurol
December 2024
Department of Otorhinolaryngology, Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.
Objectives: Multiple studies have described the onset and variable incidence of postoperative acute vertigo following cochlear implant (CI) surgery. However, postoperative imaging has not yet been specifically evaluated with special focus on vertigo. The aim of this study is to assess the incidence and causes of new-onset, acute postoperative vertigo following CI surgery using cone beam computed tomography (CBCT).

Neurology, Cantonal Hospital of Baden, Baden, Switzerland.
Background: Correct identification of those patients presenting with an acute vestibular syndrome (AVS) or an acute imbalance syndrome (AIS) that have underlying posterior-circulation stroke (PCS) and thus may benefit from revascularization (intravenous thrombolysis (IVT), endovascular therapy (EVT)) is important. Treatment guidelines for AVS/AIS patients are lacking. We reviewed the evidence on acute treatment strategies in AVS/AIS focusing on predictors for IVT/EVT and outcome.
