Case Discussion

Epiploic appendages are peritoneal outpouchings that arise from the serosal surface of the colon, contain adipose tissue and vessels, and can be up to 5 cm in length. The inflammation of epiploic appendages can be the result of torsion or venous occlusion 

The differential diagnosis of an inflammatory fatty lesion on CT includes acute epiploic appendagitis, mesenteric panniculitis, acute diverticulitis, trauma, or an omental neoplasm such as a liposarcoma 

Epiploic appendagitis does not require surgical or medical intervention. It is self-limiting. Pain can be treated with analgesics and subsides in about a week.
