Purpose - To showcase a series of secondary endolymphatic hydrops.- To highlight some of the etiologies of secondary endolymphatic hydrops.- To show the importance of imaging in the diagnosis of endolymphatic hydrops and its different causes.
Read more Methods and materials Endolymphatic hydrops (EH) is defined as the enlargement of the endolymphatic spaces within the inner ear. Its diagnostic used to be only feasible on post mortem studies and it was from the very beginnig highly associated with Ménière's Disaese (MD). Visibility on imaging was initially possible using 3T MRI scanners but with the advancement of imaging techniques and with new more powerful MRI scanners, it is now also feasible on 1.5T.Endolymphatic hydrops is usually a primary disease, with no underlying...
Read more Results All in all, we found 160 MRIs that included the late-enhanced 3D-FLAIR sequence in their protocol. Of these patients, 4 were found to have secondary endolymphatic hydrops.In all cases, patients prestented with a triade of vertigo, tinnitus and hearing loss and the diagnosis of MD was suspected.Case #1 was a patient who was suspected of having left-sided MD. On imaging, we found a dilated cochlear canal on the left side as well as an intravestibular schwannoma. We conluded to a...
Read more Conclusion A variety of ætiologies can cause secondary endolymphatic hydrops. The litterature on this subject is novel and scarce. Visualization of these ætiologies in concomittance with endolymphatic hydrops has made visible what once was only theorized. This further proves both the clinical and the scientific value of the late-enhanced 3D FLAIR sequence in understanding pressure-related inner ear diseases with the ultimate goal of earlier and accurate diagnosis for more effective treatment plans.
