Abstract

A 66-year-old male patient was referred to our hospital, because a hepatic mass had been found on CT at another hospital and confirmed as hepatocellular carcinoma by tissue diagnosis. He has never experienced any significant disease so fa. Anti-HBs, HBs antigen and anti-HCV were negative. Alpha fetoprotein level was normal. Triphasic liver CT scan revealed a 9 cm-sized, heterogenously enhanced lesion at right lobe on arterial phase. This lesion became hypoattenuation on portal phase and delayed phase. Right lobectomy for treatment was performed. We confirmed it tobe well-differenciated hepatocellular carcinoma without underlying liver cirrhosis. There was no evidence of recurrence during 2 month follow-up.
