Laparoscopic resection of a giant omental cyst masquerading as ascites

A 3-year-old child presented with huge abdominal distension mimicking ascites; no obvious localized lump was detected. She was previously hospitalized multiple times for evaluation of ascites of unknown origin. Contrast-enhanced computed tomography suggested ascites with displacement of bowel loops outside the fluid without dispersion of fluid around the liver and spleen. A diagnostic laparoscopy revealed giant omental cyst. Complete laparoscopic resection of omental cyst was performed with 4-port technique. Cyst wall was removed from the umbilical port; outcome was favorable. Laparoscopy proved to be both diagnostic and therapeutic with complete relief of symptoms.
