title: Multiple intussusceptions revealing metastases from renal carcinoma to the small intestine.
abstract: Malignant tumors of the kidney represent rare primary intestinal metastases. They occur in 4% of cases. These intestinal metastases are mainly the small intestine; colon is a rare achievement. We report a case of small intestine metastatic of a tubulo-pappilary carcinoma revealed by a multiple intussusception a year after nephrectomy. The cross-sectional imaging (ultrasound and CT) was the gold standard for positive diagnosis of intussusception and the nature of secondary underlying tumor. Intestinal metastases of renal cell carcinoma sometimes occur many years after nephrectomy. On imaging, metastases simulate all tumor aspects.
