Radiological changes in renal cell carcinoma after extracorporeal CyberKnife® radiosurgical ablation: a case report

Abstract

Small asymptomatic renal masses are more commonly discovered in elderly patients; however, multiple comorbidities in this population may preclude definitive surgical treatment. In this context, treatment options include active surveillance and ablative techniques. Stereotactic radiosurgery is a relatively innovative method of delivering ablative energy to abdominal organs, with very few human or animal experiences published. We describe our experience treating a patient with a large centrally located renal mass using CyberKnife® stereotactic radiosurgery.
