Cerebellar abscess due to Blastomyces dermatitidis.

A case of cerebellar abscess due to Blastomyces dermatitidis is reported and the literature of central nervous system blastomycosis is reviewed. The case is of interest for two reasons: 1. No obvious site of primary blastomycotic infection was found, despite an extensive search. 2. The focal blastomycotic involvement of the CNS was not associated with meningitis. Only two other such cases are explicitly reported in the literature.
