Discrepancy between Serum Ferritin and Liver Iron Concentration in a Patient with Hereditary Hemochromatosis - The Value of T2* MRI

Abstract

Primary hemochromatosis is an inherited disorder, and the homeostatic iron regulator (HFE) gene C282Y mutation is a common cause of hemochromatosis in Europe. We are reporting a case of a 56-year-old female known to have hemochromatosis with the HFE gene C282Y mutation with a serum ferritin level of 482 µg/L who underwent heart and liver T2* MRI which showed no evidence of iron overload - neither in the heart nor in the liver. This indicates that there is a discrepancy between serum ferritin and liver iron concentration by MRI and the superiority of T2* MRI in diagnosis and follow-up of iron overload in patients with hereditary hemochromatosis.
