We encountered an adult with bladder cancer that had metastasized to the jejunum, a rare mode of metastasis, inducing intussusception. A 67-year-old woman, who had undergone surgery for bladder cancer 2 years earlier visited our hospital because of to discomfort in the upper abdomen and weight loss. Ultrasonography and CT scanning of the abdomen suggested intussusception, and laparotomy was performed. Intussusception with a tumor in its front area was observed in the jejunum about 20 cm anal to Treitz's ligament. Partial jejunectomy was performed. Close examination of the abdominal cavity showed no lymph node metastasis, liver metastasis, or peritoneal dissemination. However, the tumor showed growth centerning in the submucosal layer and was a transitional cell carcinoma characterized by metastatic ability. A diagnosis of metastasis of bladder cancer was made. Intussusception due to metastasis of small-intestinal tumors is rare, and lung cancer and renal cancer have been reported as primary lesions. This intussusception has a poor prognosis.
