Intussusception up to splenic flexure by cecal carcinoma in an adult: report of a case.

A 73-year-old woman was admitted because of constipation and appetite loss. She was diagnosed as having intussusception caused by a colonic tumor, based on the results of physical examination and imaging such as ultrasonography, computed tomography and barium enema. Operation revealed that right colon from the cecum up to the hepatic flexure of the ascending colon was not fixed to the retroperitoneum, and a circular cecal carcinoma was invaginated to the splenic flexure of the transverse colon.
