Intra-operative CT scanning and post-operative biloma. a CT scanning showed ablation of the upper part of tumor thrombus in IVC and RA. b CT scanning showed ablation of the lower part of tumor thrombus in IVC and RA. c CT scanning showed ablation of the basal part of tumor thrombus in the hepatic vein. d CT scanning showed ablation of the distal part of tumor thrombus in the hepatic vein. d CT scanning showed ablation of the distal part of tumor thrombus in the hepatic vein. e CT scanning showed ablation of the tumor in segment VII. f CT scanning showed ablation of the tumor in segment VIII. g CT scanning showed biloma which was a fluid collection in the space surrounding the necrotic tissue of the ablation zone at segment VIII (black arrow). h CT scanning showed significant shrinkage of biloma 10 days after drainage (black arrow). CT: computed tomography, RA: right atrium, IVC: inferior vena cava
