Meningoencephalitis caused by Fusarium proliferatum: an unusual case.

Meningoencephalitis can be a diagnostic dilemma and one of its etiology are infectious causes including fungal agents. Fusarium species have attracted much attention as one of the invasive fungal infections. Major clinical manifestations of infections due to Fusarium spp. are broad such as keratitis, endophthalmitis, sino-pulmonary and central nervous system (CNS) infections.
