Radiofrequency ablation of a new HCC nodule in a 78-year old man with known HCC. (a) Follow-up CT image 10 years after successful percutaneous ethanol injection ablation of an HCC nodule (black arrows) reveals a new 2.5-cm HCC nodule (white arrowheads). (b) 3D CEUS image of the new nodule displaying its arterial vascularization. The nodule was treated with radiofrequency ablation, and the immediate post-procedural CEUS (c) and 24-h CT (d) images showed no residual tumor tissue, but (e) nodular recurrence (white arrowheads) was evident on the 3-month follow-up CT.
