Torsion of the omentum is a relatively rare condition and because there are no characteristic findings, this disorder is misdiagnosed in over 90% of the cases (mostly as appendicitis). We will report on a subject with severe pain in an area lower than her previous McBurney scar. An ovarian torsion was first suspected but was ruled out by ultrasonography by a hyperechoic area apart from the right ovary. Later, it was proven to be an infarcted omentum by torsion.
Symptoms of an omental torsion seldom simulate those of an ovarian torsion. This condition, however, should be included in differential diagnoses of gynecological and obstetrical emergencies. It is noteworthy that ultrasonography plays an important role in making a correct preoperative diagnosis of the omental infarction by torsion.
