Omental infarction preceded by anatomically upturned omentum.

We report the case of a 49-year-old man who presented with acute abdominal pain. Contrast-enhanced computed tomography of the abdomen revealed spontaneous omental torsion with no other noticeable findings. Notably, a computed tomography exam 6 months prior demonstrated the omentum located within the anterior hepatic space, suggesting that the patient had a hypermobile, upturned omentum. To our knowledge, this is the first case report illustrating an anatomically upturned omentum as precursor to omental infarction.
