Brief summary
The management of patients with a history of congenital CMV infection (whether symptomatic or asymptomatic at birth) is modeled on their usual management.
Detailed description
The management of patients with a history of congenital CMV infection (whether symptomatic or asymptomatic at birth) is modeled on their usual management. Patients benefit as part of the care: * A clinical cochleo-vestibular examination * Functional otoneurological explorations: audiogram, caloric tests, vHIT, otolithic evoked potentials * From an uninjected brain MRI Participation in this research entails the addition of an MRI sequence and an injection of contrast product (Gadovist®): \- 3D FLAIR MRI sequence dedicated to the exploration of the inner ear, lasting 6min30s, performed 4 hours after the initial injection of contrast product.
