Primary renal primitive neuroectodermal tumor/extraskeletal Ewing's sarcoma (PNET/EES) is a very rare renal tumor.
We report a case of primary renal PNET/EES of the kidney in an adult patient and describe its computed tomography and magnetic resonance imaging findings, including diffusion weighted images along with a review of the current medical literature.
Although very rare, a relatively large renal mass which shows very infiltrative growth pattern on CT and MR imaging and striking diffusion restriction should raise the suspicion of a renal primitive neuroectodermal tumor, in a young adult.
原发性肾原始神经外胚层肿瘤/骨外尤文肉瘤（PNET/EES）是一种非常罕见的肾脏肿瘤。
我们报告一例成年患者的原发性肾PNET/EES病例，并描述其计算机断层扫描和磁共振成像结果，包括扩散加权成像，同时回顾当前医学文献。
虽然非常罕见，但在年轻成年人中，一个相对较大的肾脏肿块在CT和MR成像上显示出非常浸润性的生长模式以及明显的扩散受限，应怀疑为肾原始神经外胚层肿瘤。
