Objective: Magnet displacement is a rare but possible complication in patients with cochlear implants. We report 1 case in a young child that occurred during magnetic resonance imaging scanning, despite precautionary measures taken by the surgeon and the radiographer.
Study design: Retrospective case report.
Setting: This case is presented by the ENT Department of Armand Trousseau Paediatrics Hospital, Paris, France.
Patient: An 8-year-old child, implanted with a Freedom Contour Nucleus cochlear implant, was referred for a 1.5-T cerebral magnetic resonance imaging because of a progressive neurologic disorder.
Conclusion: This rare complication underlines the importance of risk information and preventive measures required, even in case of compatible devices, for performing a magnetic resonance imaging examination in patients wearing a cochlear implant with removable magnet.
