Sawada I, Dhoubhadel BG, Kato K, Kawauchi N. Omental torsion: An uncommon cause of abdominal pain. Int J Case Rep Images 2022;13:101304Z01IS2022.ABSTRACT
Introduction: Omental torsion is an uncommon disease that presents with acute abdominal pain. Detailed medical history and physical examination can be sufficient for the diagnosis, although imaging techniques may verify.
Case Report: A 55-year-old woman presenting with mild fever, a right abdominal pain, and rebound tenderness at the right lower quadrant was admitted to the hospital. Although these findings implied peritonitis, she did not have gastrointestinal symptoms and had positive Carnett sign. Therefore, the pain was suspected to be associated with an abdominal wall pathology. The computed tomography (CT) scan showed the omental torsion with necrosis. Emergency laparoscopy revealed the adherence of the torsed greater omentum to the anterior abdominal wall. She was discharged without complications.
Conclusion: It is worth keeping omental torsion as a differential diagnosis in patients with acute abdomen with less prominent gastrointestinal symptoms and in patients with suspected abdominal wall pain.
