MR FINDINGS OF SECONDARY HEMOCHROMATOSIS - TRANSFUSIONAL VS ERYTHROPOIETIC

Objective: The aim of this study was to demonstrate the MR characteris tics of secondary hemochromatosis (transfusional versus erythropoietic ). Materials and Methods: Magnetic resonance images of five patients w ith transfusional (n = 3) or erythropoietic (n = 2) hemochromatosis we re reviewed. Results: The liver of all patients had low signal intensi ty in all pulse sequences. The spleen had low signal intensity in all patients with transfusional iron overload, but normal signal intensity in erythropoietic hemochromatosis, which had similar MR findings to i diopathic hemochromatosis. However, the pancreas had variable signal i ntensity. Conclusion: On MRI the signal intensity of the spleen may al low distinction between transfusional and erythropoietic hemochromatos is.
