Primary torsion of the greater omentum is a rare cause of acute abdomen commonly
diagnosed at surgery performed for appendicitis. We report nine cases of omental torsion who
underwent surgery and correlate their preoperative color Doppler ultrasonography (US) and computed
tomography (CT) findings with the surgical and pathological findings to assess the value of
US and CT in the diagnosis of omental torsion. US findings of omental torsion correlated with the
operative and pathological findings in seven patients and the diagnosis was missed in two patients
suspected to have ruptured appendix. CT findings of omental torsion correlated with the operative
and pathological findings in all five patients who did CT. US and CT scanning are useful for preoperative
diagnosis of omental torsion.
