Background:
Omental cysts are rare abdominal lesions and are difficult to diagnose. Mostly they are detected incidentally during imaging studies performed for unrelated reasons.
Case presentation:
Presentation can be both acute and chronic. Acute presentations are usually due to complication in cyst. Imaging is helpful in excluding other causes of lump abdomen. We encountered a case of giant lymphatic cyst presenting with abdominal swelling, clinically mimicking huge ovarian cyst.
Conclusion:
The goal of surgical therapy is complete excision of the cyst, and Omental cysts can be removed without endangering the adjacent bowel.
