Severe Bilateral Vertebral Arterial Disease Masquerading as Vertigo

Vertebral artery stenosis (VAS), manifesting as vertebrobasilar insufficiency (VBI), results from the narrowing of the vertebral artery's lumen because of diverse vascular pathological processes, leading to various clinical presentations. We present the case of a 71-year-old male who experienced vertigo for almost two years and was ultimately diagnosed with severe bilateral VAS. Despite initial management for vertigo, the patient's symptoms persisted, prompting a referral to a cardiologist. Several assessments were performed, including an MRI of the brain, which ruled out acute intracerebral hemorrhage or infarction. After some visits to the cardiologist's office, the patient was referred to a neurologist who conducted a magnetic resonance angiography (MRA) of the neck, which showed an occlusion of the left vertebral artery at the origin and a patent right vertebral artery. Because of worsening symptoms of vertigo and the results of the MRA, the patient underwent invasive angiography that confirmed the occlusion of the left vertebral artery and also revealed severe stenosis of the right vertebral artery. This case report discusses an unusual presentation of VAS with vertigo as the primary symptom, emphasizing the importance of recognizing seemingly minor symptoms as manifestations of the underlying vascular pathology that requires careful evaluation. Furthermore, this case emphasizes the limitation of relying solely on noninvasive imaging for diagnosis as, in this instance, noninvasive imaging failed to detect the severe stenosis of the right vertebral artery, which was revealed by invasive angiography. Finally, this case report underscores the significance of collaboration across several disciplines, such as cardiology, neurology, and radiology, as well as endovascular medicine in diagnosing and managing atypical manifestations of complex conditions.

Etiological classification and management of dizziness in children: A systematic review and meta-analysis

Background

Dizziness in children, which could not be diagnosed at an early stage in the past, is becoming increasingly clear to a large extent. However, the recognition of the diagnosis and management remains discrepant and controversial due to their complicated and varied etiology. Central and peripheral vestibular disorders, psychogenic and systemic diseases, and genetic pathogeny constitute childhood etiological entities. Further understanding of the etiology and the prevalence of vertigo disorders is of crucial importance and benefit in the diagnosis and management of pediatric patients.

Methods

This systematic review and meta-analysis were conducted by systematically searching Embase, PubMed, the Cochrane Library, CNIK, the Chinese Wan-Fang database, CBM, the Chinese VIP database, and the Web of Science for literature on childhood vertigo disorders published up to May 2022. The literature was evaluated under strict screening and diagnostic criteria. Their quality was assessed using the Agency for Healthcare and Research Quality (AHRQ) standards. The test for homogeneity was conducted to determine the fixed effects model or random-effect model employed.

Results

Twenty-three retrospective cross-sectional studies involving 7,647 children with vertigo disorders were finally included, with an AHRQ score >4 (high or moderate quality). Our results demonstrated that peripheral vertigo (52.20%, 95% CI: 42.9-61.4%) was more common in children than central vertigo (28.7%, 95% CI: 20.8-37.4%), psychogenic vertigo (7.0%, 95% CI: 4.8-10.0%), and other systemic vertigo (4.7%, 95% CI: 2.6-8.2%). The five most common etiological diagnoses associated with peripheral vertigo included benign paroxysmal vertigo of childhood (BPVC) (19.50%, 95% CI: 13.5-28.3%), sinusitis-related diseases (10.7%, 95% CI: -11.2-32.6%), vestibular or semicircular canal dysfunction (9.20%, 95% CI: 5.7-15.0%), benign paroxysmal positional vertigo (BPPV)(7.20%, 95% CI: 3.9-11.5%), and orthostatic dysregulation (6.8%, 95% CI: 3.4-13.0%). Vestibular migraine (20.3%, 95% CI: 15.4-25.2%) was the most seen etiological diagnosis associated with central vertigo in children. In addition, we found the sex-based difference influenced the outcome of psychogenic vertigo and vestibular migraine, while there was no significant difference in other categories of the etiology. For the management of vertigo, symptomatical management is the first choice for most types of vertigo disorder in pediatrics.

Conclusion

Complex etiology and non-specific clinical manifestations of vertigo in pediatrics are challenging for their diagnoses. Reliable diagnosis and effective management depend on the close cooperation of multiple disciplines, combined with comprehensive consideration of the alternative characteristics of vertigo in children with growth and development.

Low Vertebrobasilar Velocity Is Associated with a Higher Risk of Posterior Circulation Ischemic Lesions

Background: Transcranial color-coded sonography (TCCS) is used as a real-time tool to evaluate patients suspected of having vertebrobasilar insufficiency (VBI). However, the sonographic criteria for VBI remain inconclusive. The purpose of this study was to analyze the velocity in the vertebrobasilar system, which links the risk for posterior circulation infarction (POCI) and total ischemic stroke (TIS) in patients with VBI. Methods: Patients’ data were retrospectively reviewed if they were suspected of having VBI within a 2-year period. Baseline characteristics, brain images, and a series of sonography data were recorded and analyzed. We compared vertebrobasilar (VB) velocities in different age groups and in patients with infarctions. Results: A total of 875 patients were enrolled, with 112 and 427 candidates in the POCI and TIS groups, respectively. The mean velocity (MV)s of BA and bilateral VAs were all negatively correlated with age (all p < 0.001). The adjusted odds ratio was 2.55 (1.58−4.13, p < 0.001) in POCI and 1.75 (1.15−2.67, p = 0.009) in TIS if the mean velocity of the VB arteries was below 15 cm/s. Conclusions: Low VB velocity detected in TCCS was more commonly associated with ageing-related changes and a higher risk of both POCI and TIS. Recognition and aggressive treatment for these patients are necessary.

Acute Vertigo After COVID-19 Vaccination: Case Series and Literature Review

Objective: The aim of this study was to present some cases of acute vertigo potentially related to the coronavirus disease 2019 (COVID-19) vaccine and review the available literature about cochleovestibular dysfunction after the COVID-19 vaccination.

Methods: In the period from May to July 2021, we evaluated 33 patients (mean age 54.3 ± 14.1) with “acute vertigo” post COVID-19 vaccination. A detailed medical history was taken on comorbidities, types of vaccines received, and symptoms associated. All patients underwent otoneurological evaluation, such as head impulse test, nystagmus evaluation, test of skew (HINTS) examination. Head shaking test-induced nystagmus, hyperventilation-induced nystagmus, and parossistic positional nystagmus were studied to search for vestibular impairment.

Results: Symptoms included 16 patients (48.5%) with objective vertigo, 14 patients (42.4%) with subjective vertigo, and 3 patients (9.1%) with dizziness. Of the associated ear, nose, and throat (ENT) symptoms, the most expressed was tinnitus (18.2%). Bedside examination showed absent nystagmus in 7 patients (21.2%), 9 patients (27.3%) had horizontal or rotatory nystagmus, 17 patients (51.5%) had a vertical or oblique nystagmus, negative HST, or “central HINTS.”

Discussion and Conclusions: The 9 patients had an evoked nystagmus pathognomonic for benign paroxysmal positional vertigo; in the remaining 17 cases, peripheral vestibular dysfunction could be excluded and central disorder may be suggested. Due to the prevalence of nystagmus of non-peripheral origin, a central nervous system involvement could not be excluded. However, due to the small sample size, a definite cause–effect relationship between vaccination and vertigo cannot be inferred. In light of expected third dose, large-scale and well-designed studies are needed to better define possible adverse reactions of the COVID-19 vaccine.

Disability and Anxiety in Vestibular Diseases: A Cross-Sectional Study

Introduction Patients with dizziness and vertigo usually experience psychological, physical, and social functioning limitations that may affect their daily living activities. In order to better understand disability and anxiety in patients with vertigo, in the present study we aimed to investigate the correlation between disability and anxiety in four different types of diseases causing vertigo. Moreover, the difference between the observed disabilities in these etiologies of vertigo was studied. Materials and methods In this analytic cross-sectional design, 130 patients (52 male, 78 female; age range: 18-75 years) with dizziness/vertigo who were referred to our balance clinic participated. All patients underwent a detailed diagnostic procedure including neurological, clinical, and otological evaluations. Dizziness Handicap Inventory (DHI) and the Beck Anxiety Inventory (BAI) were used to assess handicap and anxiety, respectively. Results There were no significant differences in "total DHI" and DHI subcomponent scores among different study populations (p>0.05). In terms of the BAI score, the one-way analysis of variance (ANOVA) test indicated no significant differences among the four groups (p=0.158). Our results exhibited a significant positive correlation between the BAI and "total DHI" and "DHI subcomponents" values. Conclusion The degree of disability and anxiety is not different between patients with Benign paroxysmal positional vertigo (BPPV), Meniere's disease (MD), unilateral weakness (UW), and central causes. The significant positive correlation between the BAI and "total DHI" and "DHI subcomponents" values shows that the possibility of anxiety in patients with vertigo should not be ignored.

A Case of COVID-19-Induced Vestibular Neuritis

The World Health Organization (WHO) declared COVID-19, a novel coronavirus infection, as a pandemic in March 2020. Since the origin of the disease in Wuhan, China, understanding the pathophysiology, clinical presentation, screening guidelines, and management of the disease has been ever-evolving. Though respiratory pathologies have been the major complications of a COVID-19 infection, other presentations like abdominal pain, deep venous thrombosis, cardiomyopathy, and even acute cerebrovascular ischemic attacks have been reported. We present a case of a young patient presenting with vertigo, possibly from COVID-19-induced acute vestibular neuritis. This is a 20-year-old Hispanic female patient presenting with intractable vertigo, nausea, and vomiting but without any typical symptoms like fever, cough, or shortness of breath. Initial examination and imaging ruled out an acute stroke. There was minimal improvement in her vestibular symptoms with the recommended COVID-19 treatment as of March 2020 (hydroxychloroquine and azithromycin) and symptomatic management. Her inflammatory markers were surprisingly normal all through the hospital course. She was then treated with oral prednisone and subsequently discharged home after a prolonged course of eight days. The pathophysiology of COVID-19-induced vestibular neuritis could be similar to any other viral infection. Clinicians should consider COVID-19 in the differential diagnosis for patients presenting with similar symptoms, especially in areas of a high prevalence of this disease. Early diagnosis of COVID-19 in such cases is important for proper isolation, to minimize exposure and avoid further unnecessary investigations. These symptoms will just resolve with symptomatic management like any other case of vestibular neuritis without any further management that is specific for a COVID-19 infection.

Posturography studies in patients with central and mixed vertigo Summary

INTRODUCTION

The aim of the study was to compare the results of posturography in patients with central and mixed vertigo.

MATERIAL AND METHODS

50 patients (40 female and 10 male) aged between 26-47 complaining of vertigo were examined during their hospitalization in the Department of Otolaryngology, Laryngological Oncology, Audiology and Phoniatrics, Medical University of Lodz in 2014. The subjects were divided into two groups: I - 26 patients (23 female and 3 male) with central vertigo, II - 24 patients (17 female and 7 male) with mixed vertigo. The control group (III) consisted of 26 subjects, students and graduates of Lodz Universities, aged from 19 to 30, that did not complain of vertigo. The subjects were qualified to particular groups based on videonystagmography results. The examinations were conducted with "BioSway portable balance system" by Biodex.

RESULTS

In tests on a stable surface, with both closed and opened eyes, subjects with mixed vertigo coped slightly better. In tests on a sponge surface, subjects with central vertigo coped better.

CONCLUSIONS

Based on the conducted research, it may be concluded that the ability to keep balance in subjects with central and mixed vertigo is on average three times lower than in population not suffering from vertigo episodes.
