Abstract:
We report a case of Cryptococcus humicolus meningitis complicated by communicating hydrocephalus in an apparently immunocompetent 49-year-old psychiatric patient from a nursing home. He presented with a history of poor oral intake, weight loss, headache, vomiting, blurred vision, frequent falls and unsteady gait for the previous three months. He had a history of chronic cough, productive of whitish sputum for the previous month but no hemoptysis. Cerebrospinal fluid culture was positive for Cryptococcus humicolus. He was treated with intravenous amphotericin B and oral fluconazole and had clinical and microbiological improvement after three weeks of treatment. Unfortunately, the patient acquired nosocomial methicillin-resistant Staphylococcus aureus infection and died due to overwhelming sepsis.
Insights
This case study details Cryptococcus humicolus meningitis in an immunocompetent patient, complicated by hydrocephalus. Treatment showed improvement, but the patient succumbed to a secondary Staphylococcus aureus infection.
Area of Science:
- Infectious Diseases
- Neurology
- Mycology
Background:
- Cryptococcus humicolus meningitis is a rare fungal infection.
- Communicating hydrocephalus can be a complication of meningitis.
- Immunocompetent individuals can be susceptible to opportunistic fungal infections.
Observation:
- A 49-year-old nursing home resident presented with progressive neurological symptoms including headache, blurred vision, and gait disturbance.
- The patient had a history of chronic cough and poor oral intake.
- Cerebrospinal fluid analysis confirmed Cryptococcus humicolus meningitis.
Findings:
- The patient received intravenous amphotericin B and oral fluconazole, showing clinical and microbiological improvement.
- Despite initial response to antifungal therapy, the patient developed a nosocomial infection.
- The patient ultimately died from overwhelming sepsis due to methicillin-resistant Staphylococcus aureus (MRSA) infection.
Implications:
- This case highlights the potential for Cryptococcus humicolus to cause severe meningitis even in immunocompetent hosts.
- Effective antifungal treatment can lead to clinical improvement, but complications like hydrocephalus and secondary infections pose significant risks.
- The case underscores the importance of vigilance for nosocomial infections in hospitalized patients, particularly those with underlying conditions.
