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.
我们报告了后肾腺瘤的影像学表现。超声检查显示右肾有一个突出的低回声肿块。CT显示一个边界清晰的等密度肿块伴有钙化。血管造影显示完全没有新生血管形成或肿瘤染色。T1加权磁共振图像显示一个低信号肿块，在T2加权磁共振图像上略呈高信号。组织学检查显示该肿瘤为后肾腺瘤。
