A 44-year-old woman was referred to our hospital for further evaluation of a gastric deformity detected in an annual physical examination. Abdominal sonography revealed a large cystic mass in the abdomen. Computed tomography and angiographic findings strongly suggested an omental cyst with a feeder from the right gastroepiploic artery. The mass was successfully excised by the routine abdominal laparoscopic technique and was diagnosed as cystic lymphangioma by histopathologic examination. Considering its benign nature, serous content and identification of a feeder, an omental cyst would be anothre good indication for laparoscopic surgery. In other cases, laparoscopy is a useful skill for direct diagnosis.
