Case Discussion
Omental infarction on the left side of the abdomen is rare.
Torsion of the omentum is a condition in which the organ twists on its long axis to such an extent that its vascularity is compromised.
Omental infarction is caused by omental torsion which is classified as primary or secondary torsion.
- primary torsion occurs idiopathically when a mobile segment of omentum rotates around a proximal fixed point. This could be triggered by hyperperistalsis and anatomical variations of the omentum such as bifid omentum, irregular accumulation of the omental fat, redundant omental veins and narrowed omentum pedicle.
- secondary torsion occurs secondary to intra-abdominal pathology such as surgery, trauma, cysts, tumors, adhesion or hernia
