Background: Omental cysts are rarely intra-abdominal pathology. We report a case of omental cyst successfully resected by laparoscopy using two ports only with excellent outcome.

Case Presentation: Our patient was a seven year old girl who presented with complaints of lump in abdomen, in which laparoscopy aided in making a correct final diagnosis and the surgical management. Preoperative diagnostic work-up included Ultrasonography and Computed Tomography scan (CT scan) of abdomen which revealed huge intraabdominal cystic lesion of unknown origin. Extensive diagnostic workup did not reveal the etiology of his problem. Diagnostic laparoscopy led to the correct diagnosis and appropriate surgical treatment with complete relief of his complaint. Histopathology of the excised specimen was suggestive of lymphangioma.

Conclusions: On six months of follow up, the patient is doing well and asymptomatic with no evidence of recurrence.
