Abstract
A 92-year-old woman was admitted to our hospital complaining of left lower abdominal pain and bloody mucinous attachment on her underwear. The smooth tumor with irregular lesion was partly palpable at the 3 cm oral side from the anal verge. Colonofiberscopy visualized a submucosal tumor with ulcer and a type 2 tumor near the anal verge. Gastrografin enema showed the tumor as a hay-fork sign, and intussusception was not reduced by inflation. We suspected that the mass might cause intussusception. Pelvic CT revealed the low density mass at the lower rectum. Hartmann's operation was performed under a diagnosis of rectal cancer with intussusception.
We present this case with some bibliographical comments, because intussusception caused by rectal cancer is very rare.
