Disseminated Paracoccidioidomycosis with a Single Brainstem Lesion A Case Report and Literature Review

Paracoccidioidomycosis is a systemic disease endemic to subtropical areas in Central and South America caused by a dimorphic fungus known as Paracoccidioides brasiliensis. Central nervous system involvement is a severe complication of the systemic disease, and has been found in approximately 13% of patients. This paper describes the case of a patient whose computed tomography scan and magnetic resonance imaging showed a single tumor-like lesion in the brainstem. Histopathological and mycological examinations of stereotactic biopsy smears showed the characteristic yeast cells that confirmed the diagnosis of neuroparacoccidioidomycosis.
