Vasopressin induces endolymphatic hydrops in mouse inner ear, as evaluated with repeated 9.4 T MRI.
From histopathological specimens, endolymphatic hydrops has been demonstrated in association with inner ear disorders. Recent studies have observed findings suggestive of hydrops using MRI in humans. Previous studies suggest that vasopressin may play a critical role in endolymph homeostasis and may be involved in the development of Ménière's disease. In this study we evaluate the effect of vaso...
متن کاملMorphological correlation between caloric tests and vestibular hydrops in Ménière's disease using intravenous Gd enhanced inner ear MRI
The purpose of this study was to prove the hypothesis that caloric response in Ménière's disease (MD) is reduced by hydropic expansion of the vestibular labyrinth, not by vestibular hypofunction, by evaluating the correlation morphologically using an intravenous Gadolinium (IV-Gd) inner ear MRI. In study I, the prevalence of abnormal video Head Impulse Test (vHIT) results among the patients wit...
متن کاملEndolymphatic Hydrops Reversal following Acetazolamide Therapy: Demonstration with Delayed Intravenous Contrast-Enhanced 3D-FLAIR MRI.
Endolymphatic hydrops, the primary pathologic alteration in Menière disease, can be visualized by using delayed intravenous contrast-enhanced 3D-FLAIR MR imaging. It is not known whether MR imaging-demonstrable changes of hydrops fluctuate with disease activity or are fixed. We describe the results of baseline and posttreatment MR imaging studies in a group of subjects with Menière disease with...
متن کاملCASE REPORT Secondary Endolymphatic Hydrops Following Sudden Deafness Detected by MRI after Intratympanic Administration of Gadolinium
the hydrops by image analyses. A 64 years-old female who showed partial recovery of hearing disturbance two months after the onset of sudden deafness underwent inner ear MRI in combination with intratympanic injection of gadolinium. Two-dimensional fluid-attenuated inversion recovery (2D-FLAIR) sequences taken by 3 tesla MR unit showed endolymphatic hydrops in the cochlea. Electrocochleogram co...
متن کاملBrain and inner-ear fluid homeostasis, cochleovestibular-type tinnitus, and secondary endolymphatic hydrops.
Secondary endolymphatic hydrops (SEH) has clinically been found to have a significant incidence of occurrence in patients with subjective idiopathic tinnitus (SIT) of a severe disabling type. The diagnosis is made clinically and has been established by integration in a medical audiological tinnitus patient protocol of the clinical history with results of electrodiagnostic cochleovestibular test...
