title: Distinguishing splenosis from renal masses using ferumoxide-enhanced magnetic resonance imaging.
abstract: A 43-year-old man with a history of splenectomy was found to have a solid renal mass on computed tomography. Magnetic resonance imaging with ferumoxide characterized this mass as ectopic splenic tissue and nephrectomy was avoided.
