Contrast-enhanced CT scan of the abdomen in the portal venous phase performed at baseline (a), 6 weeks (b) and 12 weeks (c) after the ablation. CT scan at baseline (a) showed a heterogeneously enhancing hypodense metastatic lesion (arrow) in segment VIII. CT scan of the abdomen 6 weeks after ablation (b) revealed residual peripheral tumour with an intensely enhancing area (*) within, measuring 2.3 (width) x 1.4 (AP) cm and suggestive of a pseudoaneurysm. The pseudoaneurysm arises inferolaterally along the electrode pathway. There was resolution of the pseudoaneurysm with increased residual peripheral tumour (arrow) on the CT scan performed 12 weeks after the ablation (c).

A restaging CT scan showed a new solitary segment VIII liver metastasis measuring 3.1 (width) x 3.1 (AP) cm (Figure 1). The degree of enhancement of the lesion was similar to portal and hepatic veins (Figure 1).
