Acute cochleo-vestibular syndrome or labyrinthitis is characterized clinically by the sudden appearance of a great rotatory vertigo and a unilateral sensorineural hearing loss. In this clinical context, MRI is the examination to eliminate differential diagnoses and to make a positive diagnosis of labyrinthitis (supposedly infectious, immunologic or ischemic). The etiologies described are ischemic, infectious or autoimmune, so the risk factors are very variable (cardiovascular, autoimmune or infectious). Labyrinthitis has been little studied as a clinical entity in its own right. Indeed, studies mainly focus on sudden deafness with subgroups of patients with vertigo. The incidence of sudden deafness is of the order of 5 to 20 per 100,000 people per year but is probably under-diagnosed. The individual and medico-economic consequences are similar to those of hearing loss, with an increased risk of dementia, depression, premature death and an increase in health care consumption.

Eligibility | Inclusion criteria: - Patient of legal age (=18 years) - MRI diagnosis of labyrinthitis (presumed to be viral, immunologic, or ischemic in origin) at the University Hospitals (HUS) of Strasbourg between 01/01/2014 and 04/30/2021 - Patient with abrupt deafness (a 30 dB drop in hearing thresholds on at least 3 contiguous frequencies for at least 72 hours) associated with unilateral grand rotatory vertigo of abrupt onset - Patient with severe unilateral acute onset rotary vertigo with acute unilateral hypoacusis. - Subject who did not express his opposition, after information, to the reuse of his data for the purpose of this research. Exclusion criteria: - Subject who expressed opposition to participating in the study. - History of chronic vertigo, - Chronic dizziness, - Presence of a differential diagnosis on MRI (intra-labyrinthine shwannoma, intra-labyrinthine hemorrhage or complicated cholestatoma) - History of surgery on the inner or middle ear. |

Primary | To evaluate the performance of MRI (sensitivity and specificity) to localize labyrinthine damage in the presence of an acute cochleovestibular syndrome | The evaluation criterion is the diagnostic performance (sensitivity/specificity) of MRI for each of the structures (basal turn of the cochlea/ 2nd turn of the spire/ 3 semicircular canals, utricle and saccule) in acute labyrinthitis compared to the complementary examinations (Audiogram, VNG, VHIT, cvEMP and VVS) | Files analysed retrospectively from from January 01, 2014 to May 30, 2021 will be examined |
