Abstract
A 57-year-old man with acute myeloid leukemia (AML) French-American-British (FAB) 4 developed disseminated invasive cerebral and pulmonary aspergillosis during postinduction aplasia. According to international consensus, infection was categorized as probable (two host factors: deep neutropenia for >10 days and refractory fever for >96 h; major clinical criteria of lower respiratory tract and CNS invasive fungal infection; positive results for galactomannan antigen in three blood samples). After the failure of standard amphotericin-based therapy, the spectacular regression of multifocal brain and lung lesions was rapidly achieved under a caspofungin acetate/voriconazole combination. Further permanent caspofungin maintenance with voriconazole added during aplasia periods permitted two consolidation courses and autograft-based intensification without any delay.
