Epiploic Appendagitis

Epiploic appendagitis is thought to occur as a result of spontaneous torsion, ischemia, or inflammation of an epiploic appendage of the colon. The condition presents with acute abdominal pain that can mimic appendicitis.^[8] On helical CT, the lesion shows a characteristic appearance as an ovoid fat-attenuation focus with a hyperattenuating rim associated with the serosal surface of the adjacent colon (Fig. 12). Mild inflammatory changes of the surrounding fat may be seen.
