Central nervous system cryptococcoma in immunocompetent patients: a short review illustrated by a new case.
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.
