Background: The aim of this study is to highlight the importance of cryptococcosis as one of the most common fungal infections of the central nervous system, stressing the consideration of a cryptococcoma within the list of differential diagnosis of intraventricular masses in immunocompetent hosts.
Case description: We present the case of an immunocompetent 41-year-old female from Philippines with an intraventricular cryptococcoma due to Cryptococcus neoformans, mimicking an intraventricular primary brain tumor, who had hydrocephalus. She was approached as having a neoplastic lesion and underwent surgical resection plus third ventriculostomy through endoscopy. Later in her evolution, we realized the infectious nature of the lesion, and antifungal systemic therapy was initiated. In the end, she needed the placement of a ventriculoperitoneal shunt to maintain a good neurologic status. Despite all our efforts, she had a fatal outcome due to various complications.
Conclusion: Our case is the first intraventricular cryptococcoma due to C. neoformans, as far as we know, to be reported in English, German, or Spanish literature. Our report stresses the importance to consider this kind of infection in immunocompetent patients, to raise the level of suspicion of this diagnosis, and to know the complications and management options.
