We present 4 cases of Aspergillus fumigatus infection limited to the anastomosed artery following renal transplantation. All grafts were nephrectomized. Two patients received 2 weeks of itraconazole therapy; both showing recurrence of pseudoaneurysms following discontinuation of therapy. Another 2 patients received 3 months of itraconazole therapy without recurrence of pseudoaneurysms. Surgical interventions were life saving. Resection of infected tissues and 3 months of antifungal therapy seemed to give better results than shorter antifungal strategies.
