Background:
An 81-year-old man presented with a history of right nephrectomy for renal cell carcinoma, chronic renal insufficiency and implanted defibrillator. He was asymptomatic. Contrast-enhanced CT and MRI were contraindicated.
Investigations:

Diagnosis:
Small exophytic left midpole renal tumor, 3.7 cm in size.
Management:
Percutaneous CT-guided renal cryoablation, followed up with PET-CT imaging.
