    Cryptococcal meningitis caused severe central nervous system damage and hearing loss in a young woman, despite aggressive treatment with amphotericin B. Autopsy revealed extensive Cryptococcus neoformans infection in the brain and auditory system.

    Area of Science:

    • Neurology
    • Infectious Diseases
    • Otolaryngology

    Background:

    • Cryptococcal meningitis is a serious fungal infection affecting the central nervous system.
    • Amphotericin B is a primary antifungal agent used for treating cryptococcosis.
    • Neurological complications and hearing loss can occur in patients with cryptococcal meningitis.

    Purpose of the Study:

    • To present a case study of a fatal cryptococcal meningitis infection.
    • To detail the pathological findings in the central nervous system and temporal bones.
    • To report audiometric and vestibular examination results in the context of cryptococcal infection.

    Main Methods:

    • Case report of a 19-year-old female patient with cryptococcal meningitis.
    • Intravenous and intraventricular administration of amphotericin B.

    Related Experiment Videos

  • Gross and microscopic examination of central nervous system and temporal bone tissues.
  • Gomori methenamine silver nitrate staining for fungal identification.
  • Audiometric and vestibular function tests.

    • Main Results:

    • Despite amphotericin B treatment, the patient succumbed to cryptococcal meningitis.
    • Autopsy revealed widespread Cryptococcus neoformans cysts in the central nervous system.
    • Temporal bone studies showed neural and end-organ destruction due to fungal presence.
    • Audiometric and vestibular examinations indicated significant auditory and balance system impairment.

    Conclusions:

    • Cryptococcal meningitis can lead to devastating neurological and otological damage.
    • Fungal invasion of the central nervous system and auditory pathways can be extensive.
    • This case highlights the severe consequences of cryptococcosis, even with treatment.
