Differentiating Meniere's Disease and Vestibular Migraine: Insights from Gadolinium‐Enhanced Magnetic Resonance Imaging and Clinical Features

Abstract

ObjectiveTo explore the predictive factors between Meniere's disease (MD) and vestibular migraine (VM) by Gadolinium‐enhanced Magnetic resonance imaging (MRI) of the inner ear and Clinical Features.MethodsEighty‐seven patients (50 MD and 37 VM) underwent intratympanic injection of gadolinium and MRI was performed 24 h later. All patients underwent pure tone audiometry and caloric tests.ResultsIn the MD group, 46 (92%) of 50 patients developed endolymphatic hydrops, although only 2 (5.4%) in the vestibular migraine (VM) group had positive results groups (p < 0.001). The incidence of migraine was 14% in the MD group and 67.7% in the VM group (p < 0.001). Multivariate logistic regression of the two groups of patients indicated that the greater the sum of the maximum slow phase velocity (SPV) of the ipsilateral ear, the higher the risk of VM occurrence (p = 0.009). The incidence of carsickness was positively correlated with the incidence of VM (p < 0.001) and asymmetric hearing loss (AHL) was negatively correlated with the diagnosis of VM (p = 0.045).ConclusionGadolinium‐enhanced MRI of the inner ear is helpful for the differential diagnosis of VM and MD. Carsickness, decreased AHL, and increased Sum of the maximum SPV in the ipsilateral side (SSPVI) may act as diagnostic predictors of VM.Level of Evidence3 Laryngoscope, 134:426–432, 2024
