A 60-year-old female with hepatitis C had undergone transcatheter arterial chemoembolization (TACE) in 2010 and radiofrequency ablation (RFA) in 2011 for hepatocellular carcinoma (HCC) originated in the segment 8 of the liver. The patient was referred to our department because abdominal MRI revealed intra-abdominal lymph node swelling in 2012. The serum concentration of alpha-fetoprotein was elevated to 17.1ng/ml. FDG-PET was positive (SUV=20.15) for the swollen lymph node, but contrast-enhanced CT and FDG-PET revealed neither intrahepatic recurrences nor distant metastasis of HCC. A solitary intra-abdominal lymph node metastasis was suspected, and extirpation of the lesion was performed. The lesion was diagnosed pathologically as poorly differentiated HCC. The patient was discharged on postoperative day 17; however systemic lymph node metastasis was detected on CT four months after the operation. The patient died 14 months after the operation. We herein present a case underwent surgical resection for solitary lymph node metastasis that PET was strongly positive following RFA for HCC.
