Renal inflammatory myofibroblastic tumor: a rare tumor indistinguishable from renal cell carcinoma—report of two cases

Abstract

Renal inflammatory myofibroblastic tumor (IMT) is a rare soft-tissue tumor of controversial etiology with a potential for local recurrence after incomplete surgical resection. The radiological findings in renal IMT are not well described. We report two cases in adults with a renal mass treated with nephrectomy on suspicion of malignancy.
