Phaeohyphomycosis of Brain: Granulomatous Encephalitis Caused by<i>Drechslera spicifera</i>

Abstract

Drechslera spicifera is a dematiaceous fungus which occurs widely in nature but only rarely has been implicated in animal and human infections. Previous infections have occurred in superficial and subcutaneous sites or were encountered in immunologically compromised hosts. This report documents a case of granulomatous encephalitis due to Drechslera spicifera in an immunologically competent woman with no known underlying disease, from whom the fungus was isolated. Animal pathogenicity studies in mice reproduced the histopathologic features, and the fungus was reisolated from the animals.
