title: Renal aspergilloma due to Aspergillus flavus.
abstract: Renal aspergillomas have been reported only rarely. We report a case of Aspergillus flavus colonization of the renal pelvis and upper ureter of a patient with concomitant urinary schistosomiasis. The diagnosis was based on the demonstration of characteristic hyphal elements on direct microscopy and isolation of the fungus in culture. The patient was successfully treated with liposomal amphotericin B. This case emphasizes the importance of direct microscopic examination of urine specimens for prompt diagnosis of fungal infections of the urogenital system. Renal aspergilloma should be considered in the differential diagnosis of filling defects of the urinary tract, especially in patients who are immunocompromised.
