The cystic lymphangioma is a benign slow-growing tumor derived of the lymphatic vessels. It is presented with more frequency in the childhood and the great majority are diagnosed under 5 years of life. The most frequent localization is in head and neck, although they can be developed in any organ or soft tissue. The intraabdominal presentation is not very frequent (2-8%). The clinical presentation is very variable being the most frequent sign the appearance of an effect mass. The diagnosis of suspicion is radiological by means of abdominal ultrasonography and computed tomography. The treatment is surgical. The definitive diagnosis is always histologic. They can recidive. We present two abdominal cases that illustrate this pathology type.
