A 42-year-old woman was referred to our hospital with a complaint of abdominal pain. An abdominal CT scan revealed intussusception caused by a tumor of the sigmoid colon. The intussusception could not be unfastened by colonoscopy. Sigmoidectomy was performed. The histological diagnosis of the tumor was a benign neurogenic tumor. Adult intussusception often results from organic disease. Neurogenic tumors in gastrointestinal tract are rare.
