Abstract:
We report a rare case of localized perirenal retroperitoneal fibrosis (RPF) in a woman presenting with anemia. The increased diagnostic capabilities and imaging characteristics of CT and MRI are emphasized. Extensive search through the literature revealed that perirenal distribution of RPF has been reported in eight cases, being unilateral in only three.
