Jejunoileal fold pattern reversal (a.k.a. jejunisation of the ileum) is one of the signs of celiac disease, and is seen on small bowel follow-through studies as well as CT. The pattern is one of increased number of ileal folds and reduced number of jejunal folds , and is considered positive when there are more ileal than jejunal folds over a 5 cm distance .
