The authors describe a case of cerebral phaeohyphomycosis with lethal outcome within five weeks from surgical resection. The lesion consisted of a multilocular abscess in the left parietal lobe. The histopathologic findings showed a granulomatous reaction surrounding the abscess cavities. The causative fungus was clearly visible because of its brown-pigmented, septate, branched hyphae and spherical thick-walled cells, sometimes inside the multinucleated giant cells. Although no cultures were obtained from the exsudate, the possible diagnosis of cerebral cladosporiosis is discussed.
