Background:

Radiation colitis is a obliterans endarteritis caused by exposure to ionizing radiation. It manifests early or late in time.

Case report:

We present a case of rectal cancer treated with chemoradiotherapy and abdominoperineal resection ten years before. Patient suffered occlusive periods and colonoscopy showed stenotic colon extending from the colostomy up hepatic flexure. Colonic resection surgery was performed.

Conclusions:

It will be essential to establish a high level of suspicion that allows us to detect cases and it also will be essential to establish measures to prevent its occurrence.
