A 42-year-old patient presented with right-sided abdominal discomfort. Investigations revealed a 19 × 21 centimetres large cystic lesion occupying nearly the entire right side of the abdomen. It was situated between ascending colon and right kidney and extended from the liver to the pelvic inlet supero-inferiorly. Laparoscopic excision was planned. The cyst was aspirated completely and dissected from the surrounding structures. It was eventually found to be arising from the right free edge of the greater omentum. Due to its size and weight it was lodged behind the ascending colon. Post-operative course was uneventful. Histology revealed a mesothelial omental cyst. Omental cysts are rare abdominal tumours. Complete excision is the treatment advised to prevent recurrence. Laparoscopic excision can be safely performed taking care to ascertain diagnosis and not to damage any structures intra-operatively.

    Eitel first described omental torsion in 1899, since then, fewer than 250 cases have been reported. Although omental torsion is rarely diagnosed preoperatively, knowledge of this pathology is important to the surgeon because it mimics the common causes of acute surgical abdomen. For this reason,...
