Insights
Cryptococcal granuloma in the central nervous system (CNS) is rare in immunocompetent individuals. This study reviews cases, highlighting diagnosis and treatment of CNS cryptococcoma in non-HIV patients.
Area of Science:
- Neurology
- Infectious Diseases
- Mycology
Background:
- Central nervous system (CNS) cryptococcal infections are common in immunocompromised patients, particularly those with HIV.
- Cryptococcal granuloma (cryptococcoma) in the CNS of immunocompetent individuals is an infrequent clinical presentation.
Observation:
- This report details a new case of CNS cryptococcoma in an immunocompetent patient.
- A literature review identified 17 cases of CNS cryptococcoma in immunocompetent patients, including the presented case.
- Symptoms included symptomatic presentation despite normal immunocompetency, with some patients having comorbidities like diabetes.
Findings:
- Magnetic Resonance (MR) imaging may suggest cryptococcoma with ring-enhancing lesions, potentially with cystic changes.
- Definitive diagnosis of CNS cryptococcoma requires histopathological examination of lesion specimens.
- Treatment typically involves surgical intervention and antifungal therapy.
Implications:
- Early recognition of CNS cryptococcoma in immunocompetent patients is crucial for timely diagnosis and management.
- The location of the cryptococcal granuloma significantly influences patient outcomes.
- Further research into optimal diagnostic and therapeutic strategies for CNS cryptococcoma in immunocompetent hosts is warranted.
Objective:
Cryptococcal infection in CNS is frequently seen in HIV patients and those with other immunosuppressed conditions. However, cryptococcal granuloma in CNS in immunocompetent patient is rare. We present one new case of cryptococcoma and review literature to illustrate diagnosis and treatment of these lesions.
Methods:
We conducted literature search in Pubmed search engine of the National Center for Biotechnology Information.
Results:
Seventeen cases of CNS cryptoccoma in immunocompetent patients, including ours, have been reported to date. Of them, two patients had lesions inside spinal cord, and C. neoformans var. gattii was identified in three cases. All patients were symptomatic with normal immunocompetency although two patients had type 2 diabetes mellitus and one had torsades de pointes. Eight patients received surgical treatment and all were given antifungal agents except one suspected of teniasis.
Conclusions:
With literature reports and our experiences, we suggest that ring shaped enhancement of mass lesion with or without cystic changes in MR scan may indicate cryptococcoma, but definitive diagnosis relies on pathology study of lesion specimen. Open surgery and anti-fungal therapy should be scheduled, and outcome of cryptococcoma is largely determined by its locations.
