 Abstract
- Brain arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system in the central nervous system. The first symptom of AVM is intracranial hemorrhage, followed by headache and seizure. However, dizziness as a symptom of AVM is very rare. We report a 16-year-old female patient who presented with disequilibrium. She showed down-beating nystamgus on Dix-Hallpike test and falling tendency on Romberg test with eyes open. Magnetic resonance image showed cerebellar AVM.

Abstract
- Background and Objectives: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician’s diagnostic and therapeutic approaches for BPPV. Materials and Methods: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. Results: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). Conclusion: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.

Abstract
- Background and Objectives: Vestibular neuritis predominantly affects the superior branch of the vestibular nerve, resulting in vertigo. Acute viral labyrinthitis occurs when an infection affects both vestibulo-cochlear nerve and labyrinth, resulting in hearing changes as well as vertigo. The purpose of study is to identify there is a difference of cervical vestibular evoked myogenic potentials (cVEMP) and ocular VEMP (oVEMP) in patients with vestibular neuritis and acute viral labyrinthitis. Materials and Methods: cVEMP and oVEMP tests using 500-Hz tone-burst stimuli were performed on patients with vestibular neuritis and acute viral labyrinthitis. Pure tone audiometry, caloric test and subjective visual vertical (SVV) were performed in all patients. We compared the VEMP results, SVV, caloric test in patients with vestibular neuritis and acute viral labyrinthitis. Results: Abnormal cVEMP responses were detected in 2 (20%) patients with vestibular neuritis and 5 (100%) patients with labyrinthitis. Abnormal oVEMP responses were detected in 9 patients (90%) with vestibular neuritis and 5 (100%) patients with labyrinthitis. oVEMP abnormalities is correlated with caloric test and subjective visual vertical in patients with vestibular neuritis and labyrinthits. Conclusion: Our results shows that the response of cVEMP and oVEMP between patients with vestibular neuritis and acute viral labyrinthitis is different. We can infer that oVEMP response to air-conducted sound is different vestibular origin compared to cVEMP and may originate from utricle.

- Background and Objectives: In Meniere’s disease, the relationship between the vertigo attacks and prognosis of hearing remains unclear. Our study aimed to elucidate the possible role of recurrent vertigo in the prognosis of hearing in Meniere’s disease. Materials and Methods: The medical records of 53 patients with definite Meniere’s disease over 2 years follow-up were analyzed retrospectively and we analyzed the changes of vertigo and hearing over time. Results: While 49% of patients who were treated conservatively experienced recurrent vertigo attacks, 40% of patients did not have an episode of vertigo during the follow-up. Worsening of hearing and fluctuation were found in about 30% and 26%, respectively. There is no obvious coincidence in the course of vertigo and hearing. Conclusion: The prognosis of hearing dose not depend on the the presence of recurrent vertigo in Meniere’s disease.

Abstract

- Posterior fossa meningioma constitute approximately 10% of meningiomas. It can rarely involve the endolymphatic sac and produce symptoms of Meniere’s disease. We present the case of a 41-year-old male patient who was suffering from recurrent vertigo. The pure tone audiogram revealed low tone hearing loss on right side and temporal magnetic resonance image revealed a meningioma in posterior fossa. Posterior fossa meningioma should be considered in the differential diagnosis of patients with signs and symptoms of Meniere’s disease.

Abstract
PDF
- Acute labyrinthitis is clinically characterized by cochlear symptom like sudden hearing loss, tinnitus and aural fullness and vestibular symptom like vertigo and spontaneous nystagmus. Several disease entities may mimic labyrinthitis when the disease does not manifest its own characteristic findings. We present the case of a 43-year-old female patient who was suffering from the acute vertigo and sudden hearing loss in her right ear. The speech discrimination score in right side was 24% and brain magnetic resonance imagine revealed a mass in internal auditory canal and minimally extending cerebellopontine angle. Removal of mass was performed via translabyrinthine approach and rapid vestibular compensation was accomplished after surgery.

Abstract

- Sjögren’s syndrome (SS) can shows various neurologic symptoms as it involves the central, peripheral and autonomic nervous system. However, CNS involvement as a initial manifestation is rare. We report a 21-year old woman who presented with vertigo, gait ataxia, and hiccup lasted about one month due to a discrete dosal medullary lesion in primary SS. The symptoms and lesions improved by the intravenous methylprednisolone therapy.

Abstract
PDF
- Vestibular neuritis is commonly diagnosed by demonstrating of peripheral vestibular failure as a unilateral loss of the caloric response. It is a sudden, spontaneous, unilateral loss of vestibular function without simultaneous hearing loss or brainstem signs. In most patients with vestibular neuritis, the process is thought to involve the superior vestibular nerve. Very rarely, vestibular neuritis involves only the inferior vestibular nerve. We experienced a 56-year-old male with inferior vestibular neuritis. The patient had vertigo and spontaneous nystagmus, but a normal caloric test. Brain magnetic resonance imaging was normal, while vestibular evoked myogenic potentials had absent amplitudes on the lesion side. The patient was thought to suffer from pure inferior nerve vestibular neuritis.

Abstract
PDF
- Although vestibular neuritis is defined as acute peripheral vestibulopathy without associated hearing loss, a handful of cases reported sudden hearing loss without concurrent vertigo during follow-up of vestibular neuritis. In addition, some patients show benign paroxysmal postional vertigo(BPPV) ipsilateral to the lesion side with various interval after vestibular neuritis, and they are considered to be “secondary” BPPV. Viral and vascular etiologies have been assumed for the vestibular neuritis but, both of those failed to explain exact pathomechanism so far. Authors experienced a case of sudden hearing loss with simultaneous ipsilateral BPPV after vestibular neuritis. There has been no report of concurrent of BPPV and sudden hearing loss after vestibular neuritis. Sequential viral activations are considered to be responsible for this case.
