Metastases from renal cell carcinoma (RCC) are rarely located in the small bowel and usually present either with iron deficiency anaemia due to occult bleeding or obstructive symptoms. A 65-year-old man with not known malignancy was admitted to our hospital with symptoms of intermittent bowel obstruction. The abdominal computed tomography (CT) scan depicted a large tumour of the right kidney and obstruction of the small intestine at the level of the proximal jejunum. A jejuno-jejunal intussusception was found on laparotomy, due to endoluminal lesions that proved to be metastatic from RCC. Intussusception of the small bowel due to metastatic RCC is a very rare combination and only a few such cases have been reported so far in the literature.
肾细胞癌（RCC）转移至小肠极为罕见，通常表现为隐匿性出血所致的缺铁性贫血或梗阻症状。一名65岁不明恶性肿瘤的男性因间歇性肠梗阻症状入院。腹部计算机断层扫描（CT）显示右肾有一个大肿瘤，空肠近端水平的小肠梗阻。剖腹手术时发现空肠套叠，原因是腔内病变经证实为RCC转移灶。RCC转移导致小肠套叠是一种非常罕见的情况，迄今为止文献中仅报道了少数此类病例。
