: The optimal method for diagnosing cochleovestibular neurovascular compression syndrome(CNVC)remains controversial, and the aim of this study is to develop a standard diagnostic instrument for the condition. The clinical features of 53 sides of 50 patients with a combination of vertigo, tinnitus, and/or hearing loss were retrospectively evaluated. The following five clinical features were evaluated and given a score of 1 or 0:1)a long history of recurrent vertigo, tinnitus, or hearing loss;2)neurological findings related to positional vertigo, nystagmus, tinnitus, or hearing loss;3)neuro-otological findings involving tinnitus, audiometry, or vestibular testing;4)auditory brainstem response(ABR)evaluation with the detection of a low 25-75% II wave amplitude on the contralateral side and delayed interpeak latency in the I-III or I-V waves(usually low II wave amplitude combined with double peaks and a wide-based form)during ABR evaluation using 80 and 90dB clicks;and 5)the detection of vascular contact with the eighth cranial nerve on magnetic resonance imaging-constructive interference in steady state or air computed tomography imaging...

The objective was to evaluate nystagmus intensity and direction (NID) during bow and lean test (BLT) in subjects suffering from idiopathic lateral semicircular canal benign paroxysmal positional vertigo (LSC-BPPV), in order to differentiate between the geotropic and the apogeotropic form and to determine the affected ear before using classic diagnostic procedures. The BLT was performed in 32 subjects affected by LSC-BPPV. "Nystagmus intensity" evaluation allows distinguishing the geotropic variant from the apogeotropic one, while the "nystagmus direction" allows identification of the side...

Dizziness is a common yet imprecise symptom. It was traditionally divided into four categories based on the patient's history: vertigo, presyncope, disequilibrium, and light-headedness. However, the distinction between these symptoms is of limited clinical usefulness. Patients have difficulty describing the quality of their symptoms but can more consistently identify the timing and triggers. Episodic vertigo triggered by head motion may be due to benign paroxysmal positional vertigo. Vertigo with unilateral hearing loss suggests Meniere disease...

BACKGROUND: Fusiform aneurysms in the posterior inferior cerebellar artery (PICA) are rare and challenging to treat. Surgical treatment options for a fusiform aneurysm in the PICA include trapping with/without bypass and wrap-clipping, when elimination of the pathological wall from the systemic circulation and prevention of perforator injury are important. In addition, lower cranial nerve impairment due to surgical manipulation should also be avoided. METHOD: A fusiform-shaped aneurysm was found in a proximal part of the PICA by magnetic resonance angiography undertaken for evaluation of repeated vertigo in a 36-year-old man...

PURPOSE: Positional nystagmus is usually caused by peripheral vestibular disorder, mostly benign paroxysmal positional vertigo (BPPV). However, positional nystagmus is also encountered in central lesions. We aimed to determine clinical characteristics of the structures responsible for central positional nystagmus (CPN) associated with brain tumors. METHODS: All four patients (3 men; range=19-77years) had an evaluation of spontaneous and positional nystagmus using video-oculography...

A 56-year-old Chinese man presented with giddiness and vertigo. Subsequent chest radiography showed the classic scimitar sign of an abnormal pulmonary venous return. Further evaluation with non-contrast computed tomography substantiated the finding of a partial anomalous venous drainage pattern and identified an associated rare lung anomaly, horseshoe lung. The imaging findings of scimitar syndrome and its association with horseshoe lung are reviewed.

INTRODUCTION: Dizziness is a common symptom in general practice with a high prevalence among older adults. The most common cause of dizziness in general practice is peripheral vestibular disease. Vestibular rehabilitation (VR) is a safe and effective treatment for peripheral vestibular disease that entails specific exercises to maximise the central nervous system compensation for the effects of vestibular pathology. An internet-based VR intervention has recently been shown to be safe and effective...
