title: CT features of metanephric adenoma: a case report and review of the literature.
abstract: Metanephric adenoma (MA) is an extremely rare, benign neoplasm of the kidney. Ultrasound and computed tomography (CT) features of a case of MA in a 49-year-old woman were presented in this paper to enrich imaging manifestations of this rare entity. At plane CT, a solid mass with calcification spots was noted. After iv contrast agency, the mass showed slight irregular peripheral enhancement in the corticomedullary phase, which was obviously lower than surrounding renal cortex. Slowly filling-in was noticed in the nephrographic phase with irregular necrosis.
