Cystic metastases in renal cell carcinoma (RCC) are very rare. Very few case reports can be found in literature. Retroperitoneal cystic nodal metastases have been reported in head and neck tumors. We present a very interesting case of RCC that had disseminated intraperitoneal and retroperitoneal cystic metastases that mimicked systemic hydatidosis. A detailed color Doppler sonography was followed by plain and contrast-enhanced computed tomography on a 64-slice multi-detector scanner. Imaging features were more in favor of right RCC with cystic lymph nodal metastasis. However, rare possibility of incidental hydatid disease with RCC could not be ruled out. Biopsy from left inguinal lymph nodes was taken, which confirmed metastatic deposits from RCC.
肾细胞癌（RCC）的囊性转移非常罕见。文献中仅有极少数病例报告。头颈部肿瘤曾有腹膜后囊性淋巴结转移的报道。我们呈现了一例非常有趣的RCC病例，其出现了腹腔内和腹膜后囊性转移，酷似全身性包虫病。在一台64层多探测器扫描仪上，先进行了详细的彩色多普勒超声检查，随后进行了平扫及增强计算机断层扫描。影像学特征更支持右侧RCC伴囊性淋巴结转移。然而，不能排除RCC合并偶然发现的包虫病这种罕见可能性。对左侧腹股沟淋巴结进行了活检，证实为RCC的转移灶。
