Isavuconazole Treatment of a Patient with Disseminated Mucormycosis

We report a patient with relapsed acute myelogenous leukemia after allogeneic stem cell transplantation who developed disseminated mucormycosis due to Rhizomucor pusillus/R. miehei involving lung, brain, and skin. After failing posaconazole and being intolerant to amphotericin, he was treated effectively with isavuconazole for over 6 months despite ongoing treatment for relapsed leukemia.
