[Histoplasmosis of the central nervous system in an immunocompetent patient].

Histoplasmosis is a multifaceted condition caused by the dimorphic fungi Histoplasma capsulatum whose infective spores are inhaled and reach the lungs, the primary organ of infection. The meningeal form, considered one of the most serious manifestations of this mycosis, is usually seen in individuals with impaired cellular immunity such as patients with acquired immunodeficiency syndrome, systemic lupus erythematous or solid organ transplantation, and infants given their immunological immaturity. The most common presentation is self-limited and occurs in immunocompetent individuals who have been exposed to high concentrations of conidia and mycelia fragments of the fungi.
