A 45-year-old man was admitted for the treatment of hepatocellular carcinoma (HCC). He was diagnosed hepatitis B carrier 16 years ago and has not done a routine check. Abdominal CT showed a diffuse infiltrative HCC involving right hepatic lobe with portal vein tumor thrombosis (PVTT) involving right portal vein and proximal portion of left portal vein umbilical portion. With concurrent transcatheter arterial chemotherapy (TAC), helical tomotherapy for portal vein thrombosis was done. With these treatments, main tumor and PVTT was decreased in size markedly and no stain in hepatic angiogram. Due to repeated TAC, hepatic arterial stenosis occurred and TAC was stopped. 3 months after, recurrent tumor was detected in MRI. Radiofrequency ablation followed by High Intensity Focused Ultrasound (HIFU) was done for this recurrent mass. No viable mass was shown in the follow up MRI done 6 months after HIFU.
