An instructive case of CNS histoplasmosis in an immunocompetent host.

Histoplasma capsulatum is a dimorphic endemic fungus which infects both immunocompetent and immunocompromised hosts. Isolated CNS histoplasmosis is a rare presentation with increased risk in individuals with impaired cellular immunity, however not all patients with this condition are immunocompromised. We report a case of isolated CNS histoplasmosis in an otherwise healthy immunocompetent patient who was initially treated with Liposomal Amphotericin B followed by oral Voriconazole and later Itraconazole with significant improvement in clinical status.
