High liver FDG uptake on PET/CT in patient with lymphoma diagnosed with hereditary hemochromatosis.

Hereditary hemochromatosis is an autosomal recessive disorder of iron metabolism resulting in toxic accumulation of iron in vital organs. We present a 64-year-old white man with non-Hodgkin lymphoma treated with high-dose chemotherapy and stem cell transplant that was subsequently diagnosed with hereditary hemochromatosis. F-FDG PET/CT was performed as routine follow-up and showed a pathological finding of homogeneous increased liver glucose metabolism. Increased FDG avidity in the liver suggested the presence of damage caused by hemochromatosis.
