Imaging following cryoablation of a renal lesion.
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.


METHODS
Non-contrast CT, positron emission tomography (PET), fused PET-CT and Doppler ultrasound.
