Median umbilical fold

The median umbilical fold is a raised ridge of parietal peritoneum in the deep aspect of the anterior abdominal wall overlying the median umbilical ligament (urachal remnant). It is seen to lie between the transversalis fascia and peritoneum. It is one of five umbilical folds and should not be confused with the bilateral medial umbilical folds (which is easy to do since the name differs by a single letter).

It runs from the apex of the bladder to the umbilicus. The supravesical fossae lie between the median umbilical fold and the medial umbilical folds.
