Summary
This case report details an extremely rare instance of midbrain cryptococcal granuloma in an HIV-negative woman. Despite surgical intervention and antifungal treatment, the patient succumbed to cryptococcal meningoencephalitis.
Area of Science:
- Neurology
- Infectious Diseases
- Pathology
Background:
- Cryptococcal granuloma is a rare fungal infection, typically affecting immunocompromised individuals.
- Midbrain involvement by cryptococcal granuloma is exceptionally infrequent, presenting diagnostic challenges.
Observation:
- A 41-year-old HIV-negative female presented with a midbrain lesion initially misdiagnosed as a nodal glioma.
- The lesion, a bulky midbrain opercular formation, lacked overt signs of meningitis.
Findings:
- Surgical removal and subsequent pathomorphological examination confirmed the diagnosis of cryptococcal granuloma.
- Microbiological studies corroborated the fungal etiology.
Implications:
- This case highlights the importance of considering fungal infections in unexplained central nervous system lesions, even in HIV-negative patients.
- Despite aggressive treatment with amphotericin B and surgical intervention, the prognosis for this rare presentation remains poor, underscoring the severity of cryptococcal meningoencephalitis.
