Hepatocelluar carcinoma in an accessory lobe of the liver revealed by 11C-acetate PET with a negative finding on FDG imaging

摘要

An accessory lobe of the liver is a rare congenital anomaly, which is very difficult to diagnose preoperatively. Hepatocellular carcinoma in an accessory lobe of the liver is much rarer. We report here our findings of hepatocellular carcinoma in an accessory left lobe on 11C-acetate PET/CT images in a 67-year-old man who had both an unremarkable diagnostic contrast abdominal CT and a negative FDG PET/CT scan before the C-acetate PET/CT study.
