Massive renal infarction due to mucormycosis in an AIDS patient

Isolated renal infection by Mucor spp. occurs very rarely, even in the immunocompromised host. The mortality of the different forms of mucormycosis reaches 75-100% in most series. Infection of the kidney is usually diagnosed post-mortem. Thus, when renal infection is recognized, aggressive treatment including surgery and amphotericin B is required. We present a case in which a massive left renal infarction was the unique manifestation of mucormycosis in an AIDS patient. Administration of amphotericin B and left nephrectomy were necessary to achieve satisfactory outcome.
