It is reported that the activity of fluorodeoxyglucose-6-phosphatase which converts fluorodeoxyglucose-6-phosphatase to fluorodeoxyglucose is high in normal liver cells. However the enzyme-converting activity of glucose-6-phosphatase of well-differentiated hepatocellular carcinomas is similar to normal liver tissue. Thus using fluorodeoxyglucose in diagnosing primary hepatocellular carcinomas is difficult. However using fluorodeoxyglucose to detect extrahepatic metastasis of hepatocellular carcinomas is still possible. Case presentation We describe the case of a 45-year-old Chinese woman who developed a recurrent lesion in the chest wall from a previous surgically resected hepatocellular carcinoma. This recurrent lesion was detected first on the basis of a positron emission tomography scan then on the basis of a computed tomography scan and other clinical tests. Conclusion This finding indicates that the positron emission tomography scan is a potentially reliable tool to screen for systemic metastatic disease in patients with hepatocellular carcinomas when other cross-sectional imaging tests such as computed tomography or magnetic resonance imaging are negative. Introduction Hepatocellular carcinoma HCC is the fifth most common cancer worldwide 1 . It has a high mortality rate with most patients succumbing to the disease within one year 1 . The presence of metastatic disease in these patients markedly reduces survival 2 . Recently the occurrence of liver cancer
