[Renal aspergilloma: retroperitoneoscopic resection as a minimally invasive organ preservation treatment option].

Aspergillus infections frequently affect immunocompromised patients and are associated with high mortality. We report the case of a renal aspergilloma in a bone marrow transplant recipient. Treatment is challenging and requires a combination of systemic antifungal therapy and surgery. In the present case, a minimally invasive retroperitoneoscopic resection of the aspergilloma was performed.
