title: MRI of metanephric adenoma.
abstract: We report the imaging findings of metanephric adenoma. US examination showed a protruding hypoechoic mass at the right kidney. CT revealed a well defined isodense mass with calcifications. On angiography, neither neovascularization nor tumor staining was revealed at all. The T1-weighted MR images showed a hypointense mass that was slightly hyperintense on T2-weighted MR images. Histologically, the tumor was metanephric adenoma.
