Eitel first described omental torsion in 1899, since then, fewer than 250 cases have been reported. Although omental torsion is rarely diagnosed preoperatively, knowledge of this pathology is important to the surgeon because it mimics the common causes of acute surgical abdomen. For this reason, in the absence of diagnosed preexisting abdominal pathology, including cysts, tumors, foci of intra-abdominal inflammation, postsurgical wounds or scarring, and hernial sacs, omental torsion still can represent a surprise. Explorative laparotomy represents the diagnostic and definitive therapeutic procedure. Presently laparoscopy is the first choice procedure.
