Jiang T, et al. - To investigate the imaging characteristics of metanephric adenoma (MA) and their pathological association, authors researched the ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) findings of 11 candidates retrospectively. They noted MA with hypoechoic, slightly hyperechoic, isoechoic and with a clear boundary on US examination. Unclear boundaries, homogeneous isodensity, with calcification, necrosis, and heterogeneous hyperattenuation were observed in unenhanced CT. They recorded solid and hypovascular MA with prolonged and homogeneous mild enhancement less as compared to that of the neighboring normal renal parenchyma in all phases. MA was significantly hyperintense on diffusion-weighted MRI sequence (DWI).
