Primary Omental Torsion Is a Diagnostic Challenge in Acute Abdomen-a Case Report and Literature Review.

Torsion of greater omentum is a rare cause of acute abdominal pain. It can be primary or secondary. Secondary omental torsions are associated with a number of preexisting conditions like inguinal hernia (most common), tumours, cysts, internal or external herniation, foci of intra-abdominal inflammation and postsurgical wound or scarring. Torsion of omentum causes twisting along its long axis resulting in impaired blood supply. This condition is rare and predominant in males. Most patients are middle-aged adults. It clinically mimics acute appendicitis. If evaluated properly and diagnosed in time, good results can be achieved. We are presenting herewith a case of primary greater omental torsion and review of available literature.
