We report the first case of infection by Neosartorya hiratsukae, an ascomycete in which the conidial state resembles Aspergillusfumigatus. The fungus caused a brain infection in a Brazilian woman, who died despite itraconazole treatment. Diagnosis was established by direct microscopic examination, computed tomographic scan, and magnetic resonance imaging of the brain, and repeated cultures from the lesions. The in vitro antifungal susceptibility of the isolate is provided.
