Abstract: Ferumoxytol is a parenteral iron therapy that the Food and Drug Administration recently approved for the treatment of iron-deficiency anemia. The form of the iron, ultrasmall superparamagnetic iron oxide nanoparticles, causes T1, T2, and T2* shortening on magnetic resonance imaging, which can mimic hemosiderosis. We report such a case, with laboratory findings that demonstrate normal iron stores, and discuss the potential implications.
