Medial umbilical folds

The medial umbilical folds are raised ridges of parietal peritoneum in the deep aspect of the anterior abdominal wall formed by the underlying medial umbilical ligaments. The paired folds run from pelvis to umbilicus. The medial umbilical ligaments are anatomical remnants of foetal umbilical arteries. The supravesical fossae lie between the median and medial umbilical folds. The medial fossae lie between the medial and lateral umbilical folds.

The medial umbilical folds are variably seen on CT depending on the density of the ligament and the amount of perivesical and intraperitoneal fat. These folds can be displaced laterally by a large amount of ascites.
