title: FDG PET/CT findings in 3 cases of solitary necrotic nodule of the liver.
abstract: Solitary necrotic nodule (SNN) of the liver is a rare benign lesion that can mimic malignancy. We present 3 cases of SNN with 18F-FDG PET/CT findings. In case 1, the SNN with complete necrosis and thin fibrous capsule appeared hypometabolic. In case 2, the SNN with a large amount of necrosis and irregular thickened wall appeared hypermetabolic in the periphery. In case 3, the SNN with a small amount of necrosis appeared hypermetabolic in the whole nodule. FDG PET/CT findings reflect the histopathological composition of SNN and its evolution stage.
