On doing laparotomy the mass was not arising from ovary. Uterus and both ovaries were normal. The cystic mass was arising from omentum (Figure 3).^5,6 So simple removal of omental cyst was done and omental biopsy taken. Postoperative period was uneventful.

Discussion

Benign omental cyst is very uncommon. They can arise from greater or lesser omentum. They can be single or multiple. They contain serous or hemorrhagic or infected fluid. The cause of omental cyst is trauma, failure of lymphatic to join the venous system etc. But if it is big and present in pelvic region it can easily be mimic as ovarian tumor. Sometime it became good for the patient when we open it as malignant ovarian tumor and it come out to benign omental cyst.
