A 59-year-old man was admitted with a large amount of ascites, cake-like omental thickening, and dialysis-associated acquired cystic disease of the kidney (ACDK). It was difficult to detect renal cancer, which was revealed as a primary site of peritoneal metastases by autopsy, with conventional cross-sectional imaging, such as enhanced computed tomography and T2, T1, and dynamic gadolinium-enhanced T1-weighted magnetic resonance imaging, because multiple renal cysts caused marked distortion of the renal parenchyma and the cancer had necrosis. We demonstrated the usefulness of diffusion-weighted imaging with a high b-factor to detect renal cancer presenting with peritoneal metastasis in a patient with ACDK.
一名59岁男性因大量腹水、饼状网膜增厚和透析相关获得性肾囊肿病（ACDK）入院。通过常规横断面成像，如增强计算机断层扫描、T2、T1以及动态钆增强T1加权磁共振成像，很难检测到肾癌，而尸检显示其为腹膜转移的原发部位，因为多个肾囊肿导致肾实质明显变形，且癌症发生了坏死。我们证明了使用高b值扩散加权成像在检测一名患有ACDK且出现腹膜转移的患者的肾癌方面的有效性。
