Abstract

Cryptococcus is an encapsulated, yeast-like fungus that rarely causes infection in immunocompetent patients. We present the case report of a 66-year-old female patient with a history of rectal cancer with an isolated lumbar vertebral cryptococcosis proven by biopsy performed during operation. The patient was not an immunocompromised host and did not have any other risk factors except the history of cured rectal cancer. The presumptive diagnosis based on imaging studies was metastatic spine cancer, so operation was performed. However, cryptococcal osteomyelitis was diagnosed in the pathologic examination. This case report emphasizes that we should be aware that lumbar cryptococcosis can be a rare cause of mimicking lesions with metastatic cancer.
