Objectives: A three-dimensional (3D) inversion-recovery (IR) sequence with real reconstruction (3D-real IR) sequence 4 hours after intravenous (IV) gadolinium injection has been used to visualize the endolymphatic hydrops (ELH) in Ménière’s disease (MD). This study was designed to investigate the ELH characteristics in clinically diagnosed definite MD and to explore the pathology of MD with magnetic resonance imaging (MRI). Methods: One hundred fifty-four patients with definite MD were included in this study. All patients underwent the IV method. The grades of ELH were analyzed on each image, regions of interest of the cochlear perilymph and the cerebellum white matter were determined, and the signal intensity ratio of the former to the latter (CC ratio) on both sides in patients with unilateral MD was subsequently evaluated. Results: Endolymphatic hydrops was observed in 148 patients (96.1%) on the clinically affected side; the remaining 6 patients (3.9%) had no apparent ELH. One hundred fifteen patients (74.7%) had unilateral ELH, and 33 patients (21.4%) had bilateral ELH. Eighteen patients (11.7%) had ELH on the clinically silent side. Patients with moderate and significant grades of ELH in the vestibule and cochlea accounted for 88.3% and 90.3%, respectively. The CC ratio of the affected side (1.39 ± 0.37) was higher than that of the unaffected side (1.18 ± 0.29) ( P < .01) in 115 patients with unilateral MD. Conclusions: Moderate and significant grades of ELH are common in MD; however, the proposed diagnostic criteria are not fully consistent with ELH. The elevated contrast effect in the affected side in patients with unilateral MD may better reflect the pathologic condition of MD.

AbstractObjective:To establish a new magnetic resonance imaging scoring system for diagnosing endolymphatic hydrops.Patients and methods:A total of 214 ears of 107 patients were categorised into five groups: no symptoms, Ménière's disease, sudden deafness, delayed endolymphatic hydrops and other ear disorders. Gadolinium distribution within the labyrinth was scored separately and quantitatively by two radiologists. Multiple independent-sample non-parametric tests, Bayesian discriminant analysis, multivariate logistic regression and receiver operating characteristic curve analyses were performed.Results:The derived scoring model was highly accurate for diagnosing Ménière's disease and delayed endolymphatic hydrops. Two magnetic resonance imaging scoring methods for the perilymphatic space were proposed for the diagnosis of endolymphatic hydrops: a pre-1 value (a new variable that predicts individual probability) of more than 0.3982299, or a sum of all labyrinth component scores of less than 14.5.Conclusion:A convenient method is proposed which offers reliable radiological diagnostic criteria for Ménière's disease and delayed endolymphatic hydrops.

Abstract Several studies proposed a loss of neural structures (such as hair cells or neurons within the spiral ganglion) in Menière’s disease (MD). It has been shown that VIIth and VIIIth cranial nerves are enlarged within MD patients compared to normal controls. We now aimed to investigate potential differences in these two nerves in patients with MD. Etiology of endolymphatic hydrops, central pathological hallmark of MD, includes genetic predisposition, autoimmune processes, viral infections, cellular apoptosis and oxidative stress. We evaluated morphometric properties (long and short diameter, cross-sectional area) of the VIIth and VIIIth cranial nerves passing from the cerebellopontine angle to the inner ear modiolus, acquired on a clinical 3T magnetic resonance imaging scanner. 71 patients with MD were included, 53 of whom clinically showed a unilateral affection. Our data showed no differences in nerve morphometry between the clinically non-affected and the clinically affected side in patients with clinically unilateral MD. There was also no correlation to duration of symptoms, in contrast to previously demonstrated correlations between clinical features and the extent of endolymphatic hydrops. A disease process starting before the onset of clinical symptoms could be a potential explanation.

AbstractBackgroundRecent developments in magnetic resonance imaging have enabled demonstration of endolymphatic hydrops, and the clinical application of these imaging studies in Ménière's disease is being explored.ObjectiveTo evaluate our centre's experience to date of hydrops magnetic resonance imaging in patients with episodic vertigo.MethodsMagnetic resonance imaging was performed using a high-resolution three-dimensional fluid-attenuated inversion recovery sequence on a 3 Tesla scanner at 4 hours following double-dose gadolinium administration.ResultsThe study included 31 patients, 28 of whom had a clinical diagnosis of Ménière's disease. In unilateral Ménière's disease, magnetic resonance imaging was able to lateralise endolymphatic hydrops to the clinically symptomatic ear in all cases. Mild hydrops was often seen in clinically asymptomatic ears.ConclusionThere is a good correlation between the clinical symptoms and lateralisation of hydropic changes on magnetic resonance imaging. Further refinements of imaging techniques and grading system will likely improve the diagnostic accuracy and clinical utilisation of hydrops magnetic resonance imaging.
