Conclusion

If there is no pathognomonic radiological finding of chronic radiation enteritis, there are nevertheless several CT findings significantly associated to the disease. The most frequent are reduction of distensibility, marked bowel wall enhancement, extended length disease (more than 20 cm), continuous disease and retraction of bowel loops.

Two main CT patterns are evocative of the disease, which are (pattern 1) extended and continuous disease, reduction of distensibility, homogeneous enhancement and retraction of bowel loops, and (pattern 2) reduction of distensibility with layered and marked bowel wall enhancement and thickening bowel wall. Pattern 1 is highly associated with surgery.
