In patients presenting with symptoms of endolymphatic hydrops, signs of vestibular dilation are often found on MRI. Some patients present with these radiological signs without vestibular clinical signs, or signs other than those of hydrops. No study has yet investigated the radiological-clinical correlation of endolymphatic hydrops by selecting patients based on their imaging findings and then comparing them to the symptoms presented.
