OBJECTIVE: To examine endolymphatic hydrops (EH) using magnetic resonance imaging (MRI) in @entity1 with definite @entity195 ( @entity601 ) and those with nonotological diseases. METHODS: We studied 32 @entity1 with unilateral @entity601 , 10 @entity1 with bilateral @entity601 and 21 @entity1 with control ears who had other benign diseases not associated with @entity393 . The mean age of the subjects was 54.0 years (range 27-74) in the @entity601 group and 56.1 years (range 24-79) in the control group. Using MRI, the degree of EH was classified as none, mild and significant in the cochlea and vestibule separately. The ratio of the area of endolymphatic space to the vestibular fluid space was calculated for the vestibule. The duration of @entity601 was defined as the months between the first attack of @entity601 and the MRI study. RESULTS: EH was present in the cochlea of 45/52 affected ears of @entity1 with @entity601 (87%) and in 16/42 control ears (38%). Significant @entity18129 was present in 37/52 affected ears (71%) and in 4/42 control ears (10%). EH in the vestibule was present in 49/52 affected ears (94%) and in 3/42 control ears (7%). Significant vestibular hydrops was present in 40/52 affected ears (77%) and in none of the 42 control ears. There was no relationship between the degree of EH and its duration. Using a cut off value for the relative size of EH in the vestibule of 41.9%, the test had a sensitivity of 88.5% and a specificity of 100% to diagnose definite @entity601 . CONCLUSION: Cochlear EH was occasionally observed in control ears on MRI, as in normal temporal bone specimens. The presence or absence and degree of vestibular EH were significantly different between ears with @entity601 and control ears. EH in the vestibule might be a specific predictor of definite @entity601 .
