The diagnosis of endolymphatic hydrops is usually made based on clinical symptoms with some assistance from otological functional tests. Recently, the objective diagnosis of endolymphatic hydrops by MR imaging has become possible and many research results have been reported regarding the imaging methods, evaluation methods, the correlation between imaging results and functional otological tests and the correlation between imaging findings and clinical symptoms.

Endolymphatic hydrops may occur as a result of trauma such as a blow to the head, infection, degeneration of the inner ear, allergies, dehydration and loss of electrolytes or in extremely rare circumstances a benign tumor such as an endolymphatic sac tumor. In many cases, it is not clear what causes the disorder. Endolymphatic hydrops is currently routinely visualized using 3-T magnetic resonance imaging (MRI) 2 4 hours after intravenous administration of gadolinium (Gd). Using this in vivo imaging method, we characterized EH enlargement in patients with MD during medical treatment. 3 Herein we describe a 4.5-year course of MD in a patient in which EH was repeatedly observed. Severe vestibular endolymphatic hydrops (EH) and cochlear EH in the left inner ear.

Summary: 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 Keywords: Magnetic Resonance Imaging, Endolymphatic hydrops, Temporal bone disease, Menière's disease, Classification, Diagnosis How to Cite: Bernaerts A.

Different studies have investigated the correlation of MRI EH findings with clinical and cochleovestibular tests, for validation and evaluation of treatment response in patients with Ménière’s disease. As endolymphatic hydrops occurs mainly in the cochlea and balloon and less frequently in the utricle and semicircular canal [17, 18], our assessment was limited to the cochlea and the vestibule. A significantly higher detection rate for endolymphatic hydrops in the cochlea, especially in the apical turn, was achieved for the 3D real IR sequence Endolymphatic hydrops (EH) become visible in vertigo patients, particularly in those with Meniere's disease (MD), in vivo using gadolinium-enhanced MRI. However, the image quality is not satisfying after intravenous injection of gadolinium chelate (GdC), and occasional failure in GdC uptake has been noticed after traditional intratympanic injection. Objective: To standardize the evaluation of endolymphatic hydrops in both the vestibule and the cochlea using MRI. Patients and methods: The endolymphatic space was evaluated after intratympanic gadolinium injection using three-dimensional fluid attenuated (3D-FLAIR) MRI and three-dimensional real inversion recovery (3D-real IR) MRI. Endolymphatic sac decompression is a treatment that is performed to maintain the hydrostatic pressure and endolymph homeostasis in the inner ear for patients with Meniere’s disease. This procedure can reverse the damage to the ear while maintaining the balance of your hearing levels.

EH is indeed a condition characterized by a distension of the structures filled with endolymph. The cochlear duct, the saccule, the utricle or ampullae contain endolymph.
