ABSTRACT
A 57-year-old male with history of thalassemia intermedia and hepatocellular carcinoma underwent a positron emission tomography/computed tomography (PET/CT) scan with 18F-choline before radioembolization procedure with 90Y-microspheres. The PET/CT scan with 18F-choline demonstrated highly increased tracer incorporation within a gross lesion in the hepatic dome coupled with diffuse activity in bone marrow, this latter aspect was probably due to the compensatory hematopoiesis stimulation induced by chronic hemolysis. This pattern of skeletal 18F-choline uptake should be considered as a peculiar PET/CT finding in thalassemic patients.
