Case Discussion

Mesenteric cystic lymphangiomas are rare intra-abdominal masses with a reported incidence of approximately between 1/20,000 and 1/250,000, usually located in the retroperitoneum, followed by mesentery.

On CT, mesenteric lymphangiomas appear as uni- or multilocular masses without enhancement or with mild enhancement of the septae.
