Positron emission tomography/computed tomography (PET/CT) images showed background level 18F-FDG uptake in the mass lesion. In addition, a secondary focus of increased 18F-FDG uptake was detected on the left liver lobe, segment 2, approximately 1,5 cm in diameter. Histopathological examination revealed HCC in the larger mass lesion with a lower 18F-FDG uptake, and cholangiocellular carcinoma in the smaller mass lesion with a higher 18F-FDG uptake. To our knowledge, this is the first case report of two histopathologically different primary malignant liver tumors in two distinct segments of the liver detected by PET/CT.eninfo:eu-repo/semantics/openAccessArticleWOS:00044671100000710.4274/mirt.9372330317851trdizin
