Combined Hepatocellular Carcinoma and Cholangiocarcinoma With High F-18 Fluorodeoxyglucose Positron Emission Tomographic Uptake

摘要

A 34-year-old woman was hospitalized for further evaluation of a space-occupying lesion in the liver. Ga-67 SPECT showed increased accumulation of isotope in the tumor periphery. Fluorine-18 Fluorodeoxygluclose (F-18 FDG) positron emission tomography (PET) revealed a ring-like accumulation of isotope at the tumor periphery, and the standardized uptake value was 8 to 11. A mixed type of combined hepatocellular carcinoma and cholangiocarcinoma was diagnosed.
