A case of immunocompetent intracranial cryptococcoma in which intraoperative rapid pathological diagnosis and polymerase chain reaction led to early treatment: What to know to avoid misdiagnosis as brain tumor

Cryptococcal infections of the central nervous system are infrequent in immunocompetent hosts and usually present as meningitis. However, a fungal mass called a cryptococcoma may form, requiring caution in therapeutic intervention. Here, we report a rare case in which treatment of intraventricular cryptococcoma in an immunocompetent patient was facilitated by rapid pathological diagnosis.
