(a) Follow-up CT scan obtained 1 day after RF ablation shows the ablated area with peritumoral hyperemia (arrow) in the left lateral segment of the liver. (b) Follow-up CT scan obtained 6 months later shows multiple extrahepatic and intraperitoneal tumor nodules (arrows) just below the site of ablation.
