ABSTRACT
Cryptococcal infection of the central nervous system (CNS) typically affects patients with HIV infection. In addition, opportunistic infections can also occur during immunosuppressive therapies. Some patients develop cryptococcal meningitis. Cryptococcomas, however, are rarely observed. A 42-year-old patient with sarcoidosis known for 2½ years presented with a cerebral mass lesion primarily thought to be CNS sarcoidosis. Stereotactic biopsy and extensive micro- and macrobiological investigations revealed a cryptococcoma which had emerged from cryptococcal meningitis despite 3 months of treatment. Differential diagnosis of cerebral cryptococcoma is difficult due to the unspecific findings in the CSF analysis if C. neoformans fails to be detected using Indian ink staining or PCR studies. In this case, stereotactic biopsy and pathohistological examination revealed C. neoformans causing intracerebral mass lesion. Intensive treatment with antifungal drugs was followed by remission of all symptoms. In conclusion, cryptococcoma of the CNS represents a very important indication of mass lesions in patients suffering from sarcoidosis and treated with corticosteroids.
