Giant omental lipoma arising from broad ligament mimicking as adnexal mass: a diagnostic dilemma

Lipoma is a benign mesenchymal tumor composed of adipose tissue encapsulated by connective tissue. Omental lipoma can cause large intra-abdominal mass which itself a rare finding (Li JXJ, Giddings HL, Owen G. Omental lipoma: a rare cause of a giant intra-abdominal mass. <i>J Surg Case Rep</i> 2022;<b>2022</b>:rjac160. 10.1093/jscr/rjac160). It can be present as mass in area around ovaries and fallopian tube mimicking adnexal mass. We hereby describe a case of a 40-year female who presents as non-specific abdominal pain, sensation of heaviness in pelvic region, and increase frequency of micturition, with further imaging, modality omental lipoma was encountered, exploratory laparotomy mass arising from broad ligament and complete excision was performed. Further confirmed by histopathology examination.
