Abstract

Cryptococcosis is a systemic mycosis caused by fungi of the genus Cryptococcus, with Cryptococcusneoformans and Cryptococcus gattii being the main species of medical importance. Although they share similarities, they show clinical and pathogenic differences due to structural and immunological variations and distinct mechanisms of evasion of the host response. We report the case of a 44-year-old woman with no known immunosuppression. She was initially referred for suspected neurocysticercosis and was nevertheless diagnosed with disseminated cryptococcosis caused by C. gattii, characterized by multiple pseudocysts in the central nervous system, a large pulmonary cryptococcoma, and an ulcerated skin lesion on the shoulder. The treatment included prolonged antifungal therapy, a lumboperitoneal shunt, resection of the lung mass, and corticosteroid therapy. After a lengthy hospital stay, the patient improved clinically and was discharged; however, she had neurological recurrences that required further hospitalizations, later evolving to death.
