摘要: The number of percutaneous radiofrequency ablation procedures performed for renal tumors is progressively increasing worldwide. Periodic imaging follow-up has the double role to guarantee treatment efficacy over time and early detect any possible complication. Tumor size reductions, as well appearance characteristic 'halo sign', are normal findings that represent good ablative outcomes. However most reliable factor remains total absence contrast enhancing zones within ablated area. aim this article illustrate typical aspect an effective treatment, which may suggest presence residual tumoral tissue main late procedural complications.
