Abstract: 
Introduction
Omental torsion is a rare cause of acute abdominal pain caused by twisting of the omentum along its long axis, thus compromising its vascularity. Its presentation is non-specific and can mimic other common pathologies, making its pre-operative diagnosis challenging.

Presentation of case
A 44-year-old female presented for periumbilical abdominal pain. Her laboratory results showed no leukocytosis and CRP was within normal range. CT scan of the abdomen and pelvis with oral and IV contrast showed a well demarcated pericecal mass at the right side, mostly suggestive of transmesenteric internal herniation with strangulation. The patient eventually required laparoscopic surgical intervention.

Discussion
The acute abdominal manifestations in patients with omental torsion are due to the development of edema and necrotic tissue distal of the torsion after the arterial supply and venous drainage have been obstructed. Rotation around the right gastroepiploic artery is considered to be the most common cause of omental torsion. Primary torsion is considered to be idiopathic, while secondary torsion occurs due to an identifiable predisposing pathology such as omental cysts, hernias, adhesions, or intra-abdominal tumors. Since symptoms of omental torsion are non-specific, it is crucial to consider the differential diagnosis and rule out other causes of acute abdomen. Surgical intervention is the mainstay treatment when there is uncertainty in the diagnosis, or when the patient's clinical, radiological, and laboratory findings worsen with conservative treatment.

Conclusion
Early surgical intervention in cases of omental torsion reduces the incidence of formation of abscesses, adhesions, and omental necrosis. In cases of non-operative candidates, conservative treatment is the best option; therefore, the choice of treatment of omental torsion should be considered on a case-by-case basis.
