Renal cell carcinoma (RCC) spreads predominantly by direct extension, lymphatic dissemination, or venous invasion. Intraperitoneal metastatic spread of RCC involving mesentery and omentum is very uncommon. We report three unusual cases of RCC in which widespread diffuse intraperitoneal metastases were present at the time of diagnosis. The CT findings in these cases included extensive ascites, widespread omental infiltration, and peritoneal implants, as well as retroperitoneal metastases.
肾细胞癌（RCC）主要通过直接蔓延、淋巴扩散或静脉侵犯进行转移。RCC累及肠系膜和大网膜的腹膜内转移扩散非常罕见。我们报告了3例不寻常的RCC病例，这些病例在诊断时就已出现广泛的弥漫性腹膜内转移。这些病例的CT表现包括大量腹水、广泛的大网膜浸润、腹膜种植以及腹膜后转移。
