Ménière’s disease (MD) is a common chronic condition characterised by fluctuating low-frequency hearing loss, intermittent vertigo, tinnitus and ear fullness.

Endolymphatic hydrops (EH) refers to the pathological dilatation of the endolymphatic component of the inner ear, which distends into areas that are normally occupied by the perilymphatic space. It has been recognised as the anatomical and pathological hallmark of MD, although it is also present in other inner-ear diseases.

Until recently, EH could only be confirmed at autopsy, which is rarely performed for inner ear pathology, limiting the investigation of MD and other EH-related inner ear diseases.

Recent advances in MRI methods have provided in vivo evaluation of endolymphatic hydrops that could be of outstanding interest in these patients. These techniques have moved from research into clinical fields and should be implemented in radiology departments dealing with such patients.

Severe vestibular endolymphatic hydrops (EH) and cochlear EH in the left inner ear.

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. However, different scales have been used for EH grading in these articles, thus limiting reproducibility and comparability. For this reason, the aim of our study was to analyse the degree of inter-observer agreement on the detection and grading of EH in the cochlea and vestibule of patients with unilateral definite Ménière’s disease, with different scales, and to determine the correlation with clinical information, in order to establish the recommended scale and give some information about comparability.
