A diagrammatic illustration showing the anatomical relationship of the bowel loops in an intramesosigmoid hernia. The bowel herniates through a defect in the medial leaf of the mesocolon (white arrow) into a sac formed by the lateral leaf of the mesocolon (black arrow). The herniated bowel is found anterior to the left psoas muscle (*) and posterior to the sigmoid.
