meningitis following head injury after cochlear implantation: A case report

Abstract

Bacterial meningitis is a rare event in children with cochlear implants. A 7-year-old child who underwent cochlear implantation (CI) for the right ear 6 years ago was admitted to our hospital with the chief complaint of intermittent fever and headache for 6 months. Cochlear implant infection was suspected. The right cochlear implant removal and middle ear exploration were performed. Postoperatively, the bacterial cultures of cerebrospinal fluid (CSF), cochlear implant and inserting electrodes all suggested Pseudomonas aeruginosa . The body temperature of the child was controlled within 2 weeks after the operation by using meropenem, and other symptoms like headache and abdominal pain disappeared. During 20-month follow-up visit, the child did not suffer any discomforts. In conclusion, we reported a child who developed Pseudomonas aeruginosa meningitis following head injury after CI. This case should serve as a reminder for clinical doctors.
