Early bilateral eighth nerve involvement in meningococcal meningitis
Abstract:
A male Navy recruit had hearing loss and bilateral otitis media. Meningeal signs, not initially present, developed approximately 48 hours after admission to the hospital. Type Y meningococcus was isolated from blood cultures drawn after two days of ampicillin administered orally. Permanent, bilateral, vestibular and auditory loss resulted, in spite of adequate doses of penicillin. This unusual presentation of bilateral eighth nerve involvement was thought to be due to a localized, bilateral meningococcal labyrinthitis.
Insights
A Navy recruit developed meningitis with hearing loss and vestibular issues. Despite treatment, permanent bilateral auditory and vestibular loss occurred, suggesting meningococcal labyrinthitis.
Area of Science:
- Neurology
- Infectious Diseases
- Otolaryngology
Background:
- A male Navy recruit presented with hearing loss and bilateral otitis media.
- Meningeal signs developed 48 hours post-admission.
Observation:
- Type Y meningococcus was isolated from blood cultures after oral ampicillin treatment.
- The patient received adequate doses of penicillin.
Findings:
- Permanent, bilateral, vestibular, and auditory loss resulted.
- This case demonstrated unusual bilateral eighth nerve involvement.
Implications:
- The presentation suggests a localized, bilateral meningococcal labyrinthitis.
- This highlights the potential for severe neurological and auditory complications in meningococcal infections.
