Abstract:
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.
Insights
Microwave ablation offers a promising, less invasive alternative for treating invasive aspergillosis in immunocompromised patients. This technique, used alongside antifungal therapy, shows potential for managing difficult renal aspergilloma cases.
Area of Science:
- Medical Mycology
- Interventional Radiology
- Infectious Diseases
Background:
- Invasive aspergillosis incidence is rising due to increased immunocompromised populations.
- Despite antifungal advancements, invasive aspergillosis carries high morbidity and mortality.
- Surgical debulking is effective but limited by patient comorbidities, necessitating non-invasive alternatives.
Observation:
- Microwave ablation presents advantages like rapid heating and high temperatures for ablative therapies.
- A case of angioinvasive renal aspergilloma in an immunocompromised patient is presented.
- This case explores microwave ablation as an adjunct to medical management.
Findings:
- Microwave ablation demonstrated potential as a minimally invasive treatment option.
- The technique was successfully applied as an adjunct to standard antifungal therapy.
- High intra-lesion temperatures achieved by microwave ablation may enhance therapeutic efficacy.
Implications:
- Microwave ablation could expand treatment options for invasive aspergillosis, particularly in renal sites.
- This approach may offer a viable alternative for patients unsuitable for surgery.
- Further research into microwave ablation for invasive fungal infections is warranted.
