Case Report

Interventional Magnetic Resonance Image-guided Percutaneous Cryoablation of Renal Tumors

Authors: Patrick E. Sewell, MD, Jeffrey C. Howard, MD, W. Bruce Shingleton, MD, R. Brent Harrison, MD


We describe the first two cases of percutaneous cryoablation under magnetic resonance imaging guidance. To date, this minimally invasive procedure has been used for the treatment of renal cell tumors in patients who cannot tolerate or refuse surgical nephrectomy. The two patients described showed no evidence of recurrence or complications 35 and 36 months after the procedure.
