Abstract

Over the last few years, percutaneous radiofrequency (RF) ablation has been successfully established as a viable treatment modality for small peripheral renal cell carcinoma (RCC). This technique is limited by central tumor location and tumor size. We report the interventional management of a 5.3 cm mixed RCC with central and exophytic parts by combining the RF ablation with embolization, tagging, and retrograde, as well as anterograde cooling. The potential pitfalls of complex hybrid interventions for treating RCC are discussed.

  Fig. 1 Renal tumor before (arrows in A), during (* in B), and after (arrows in C) embolization of its central part with iodinated oil. Embolization was focused on central part of mixed tumor in order to achieve sufficient tagging of this area. Multi-planar reformations from intra-procedural CT images (D, E) illustrate positioning of radiofrequency probe and its relation to cooling catheters (* in E, F = RF probe; arrowhead in E = internal catheter; arrows in E = external cooling catheter). Central part of tumor reaches collecting system, which is marked by external cooling catheter. Follow-up CT scan eight months after intervention reveals no signs of local tumor recurrence (F). Note residual iodinated oil at site of ablation (arrows).
