Cerebellar cryptococcoma in an immunocompetent adult patient.

Isolated cerebellar cryptococcoma in an immunocompetent patient is a rare condition. We report a case of an immunocompetent adult with isolated cerebellar cryptococcoma. The patient presented with chronic headaches for one year and was found to have multiple cerebellar abscesses on imaging. Our patient underwent resection of the lesion and the cryptococcoma was subsequently diagnosed by histological examination. We initiated treatment with antifungal medicine and was successfully treated after 6 months of therapy. A cryptococcoma may be a cause of isolated cerebellar abscess in immunocompetent patients despite not finding cryptococcal antigen in the serum.
