It increases progressively in length as it ranges distally. It traverses laterally in a transverse plane as it relates to the posterolateral aspect of the colon and fuses with the lateral parietal peritoneum at which it lines the paracolic gutter .
It is seen at the lateral fusion of anterior and posterior perirenal fasciae at the level of the ascending and descending colons. It can be seen in CT on axial cuts. It has a variable length and can be seen at a level just below the liver or spleen .
History and etymology
Two American anatomists Edgar D Congdon and John N Edson first named it due to its location lateral to the perirenal space, and therefore the perirenal fascia, which is also known as the cone of renal fascia as it tapers inferiorly.
