A case of secondary hemochromatosis with high uptake of liver in F-18 FDG PET/CT imaging.

摘要

Hemochromatosis is an iron storage disorder with progressive and massive deposition of iron in the parenchymal cells of various organs. A 72-year-old woman with rheumatoid arthritis diagnosed with secondary hemochromatosis underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography(PET)/computed tomography (CT) to search for malignancy. F-18 FDG PET/CT incidentally showed homogeneous and high FDG uptake (mean SUV, 4.8) in the liver with high density. FDG uptake seemed to be reflected by the functional abnormality of liver. Hemochromatosis should be considered when making a diagnosis of homogeneous high F-18 FDG uptake in liver with high density on CT image.
