[en] Epiploic appendagitis is the term used to describe the inflammation of an epiploic appendage. These small masses of fat distributed along the colon, from the caecum to the recto-sigmoid junction can inflammate by torsion, spontaneously or secondarily with the inflammation of an anatomical structure in the neighbourhood. Symptomatology may mimic retro-caecal appendicitis or diverticulitis and the diagnosis by CT avoids unnecessary surgery or hospitalization. Indeed, under conservative treatment by AINS and analgesics, symptomatology regresses in about five days. In this article, we relate the case of a patient with a typical clinical presentation, to remind the elements of this pathological entity.
