RESUMO
Increasing numbers of immunocompromised patients have led to a corresponding rise in the incidence of invasive Aspergillus infections. Despite advances in antifungal therapy coupled with reduction in immunosuppression, invasive aspergillosis is associated with significant morbidity and mortality. Although surgical debulking has proven effective in difficult-to-treat cases, patient comorbidities may prevent such intervention. Non-invasive alternatives to surgery are needed. Microwave ablation has many advantages over other ablative techniques, including convection profile, faster heating time, and higher intra-lesion temperatures, which may be associated with greater therapeutic efficacy. We report a case of microwave ablation as an adjunct to medical therapy in angioinvasive renal aspergilloma.
