Radiofrequency thermal ablation of a splenic metastasis

B J Wood et al. J Vasc Interv Radiol. 2001 Feb.

Abstract

Effective local ablation of large tumors with radiofrequency has been made possible by recent advancements. Tumor ablation with radiofrequency has been described mainly in the liver, but also recently in the kidney, adrenal gland, lung, and breast. A rapidly growing splenic metastasis from renal cell carcinoma was effectively treated percutaneously, with US guidance. Focal splenic disease may not be a common indication for ablation; however, further work is necessary to evaluate the safety and efficacy of this procedure in this setting.

Pretreatment CT scan shows an enhancing, low-attenuation splenic metastasis from renal cell carcinoma (arrow).

Figure 2
T2-weighted (repetition time = 3,000; echo time = 112) MR of the splenic metastasis/thermal lesion (large arrow) immediately after ablation shows no enhancement and diffuse low signal consistent with coagulative necrosis. The needle track was cauterized as the probe was removed, resulting in the tear-drop shaped thermal lesion, whose apex corresponds to the needle track (small arrow).

Contrast-enhanced CT scan of thermal lesion and scar (arrow) at 6 months after ablation. The thermal lesion is much smaller but retains similar shape.
