Giant cavernous mesenteric lymphangioma in adult.

Lymphangiomas are uncommon benign tumors and occur mainly in children and are usually located in head and neck. The abdominal organs are uncommon sites of origin. Usually they are asymptomatic and are diagnosed incidentally by physical examination due to abdominal pain or palpable mass or by radiologic imaging. Although benign, they can have a potentially aggressive behavior and necessitate surgical resection. On CT scan lymphangiomas appear as uni-multilocular septate cystic masses with enhancement of the wall and septa by contrast medium while MRI permits to detect lipids within the cystic lesions.
