Figure 4. — Local tumor recurrence after transarterial chemoembolization (TACE) in a 63-year-old woman with hepatocellular carcinoma. (A) Enhanced magnetic resonance (MR) images show a 3.5-cm-sized hypervascular tumor at segment 6 of the right hepatic lobe (arrow). (B) Spot radiograph obtained after TACE shows a tumor stain (arrow) with prominent portal veins in the embolized area (arrowheads). (C) Cone-beam computed tomography (CT) scan obtained immediately after TACE shows dense iodized oil accumulation in the tumor (arrow). The anterolateral tumor aspect was not completely covered by parenchymal iodized oil deposition (arrowheads), which was classified as grade B. (D) Unenhanced CT scan obtained 1 month after TACE shows dense iodized oil accumulation in the tumor (arrow). (E) Enhanced MR images obtained 4 months later showed tumor recurred at a site without an adequate safety margin (arrows) (peritumoral recurrence).
