Endoscopic ultrasound diagnosis and laparoscopic excision of an omental lymphangioma

Omental lymphangiomas are rare intra-abdominal tumors. We describe a case of an omental lymphangioma which appeared on computed tomography scan as a possible gastric duplication cyst. The lesion was correctly diagnosed preoperatively via endoscopic ultrasound and complete excision of the cyst was performed laparoscopically.
