Epiploic appendix
The epiploic appendices are small pouches of the peritoneum filled with fat and situated along the colon, but are absent in the rectum.
They are chiefly appended to the transverse and sigmoid parts of the colon, however, their function is unknown.
The appendages can become inflamed, a benign but painful process known as epiploic appendagitis which can mimic acute appendicitis and other conditions.
