The colon is often affected by radiation for pelvic genitourinary tract tumors. Radiation colitis typically develops after 2-years latent period. Patient presents with rectal bleeding, pain and diarrhea.
Barium enema examination can show diffuse or focal narrowing of the rectum and sigmoid colon, usually with tapered margins. The mucosal pattern is usually preserved but may be distorted or disrupted because of edema or intramural hemorrhage.
