A case of rectal cancer with intussusception

Abstract

An 85-year-old woman was hospitalized for lower abdominal and perianal pain. There was no evidence of intestinal obstruction ; a type I tumor was observed in the rectum on endoscopy. Computed tomography showed a mass with a multiple concentric ring sign in the rectum. A diagnosis of rectal intussusception due to rectal carcinoma was established, and an operation was performed. Manual reduction was tried at first, but was not successful. Therafore, Hartmann's operation was performed. In adults rectal carcinoma presenting as intussusception is extremely rare. Thus, we present this case and discuss the relevant literature.
