Adrenal hemangioma‐adenoma: An exceedingly rare adrenal collision tumor

Adrenal collision tumors are rare clinical entities referring to separate coexisting adjacent tumors involving an adrenal gland with sharp demarcation between the two and without a substantial histologic admixture at the interface. We report a case of a 60‐year‐old female patient with an exceedingly rare adrenal hemangioma‐adenoma collision tumor. To our knowledge, this is the first report of a collision tumor comprising an adrenal hemangioma and an adenoma. J. Magn. Reson. Imaging 2009;29:949–952. © 2009 Wiley‐Liss, Inc.
