Transurethral passage of Aspergillus fungus balls in acute myelocytic leukemia.

: A patient with acute myelocytic leukemia who had a chronic febrile illness during the induction of remission of leukemia developed asymptomatic discrete pulmonary infiltrates which rapidly evolved into cavities containing homogeneous opacities. Over the next five weeks, the cavities resolved without specific treatment. The patient subsequently passed large fungus balls in the urine, and the diagnosis of disseminated aspergillosis was made. A course of intravenous amphotericin B therapy was completed without complications. This case demonstrates the importance of culturing urine specifically for fungal organisms in the immunosuppressed host.
