Typically, cystic lymphangioma is located in tissues soft of the head and neck on the other hand the intra-abdominal location is very unusual with a percentage of 2 to 3% whose location mesenteric remains the most common followed by the omentum then the mesocolon and finally the retroperitoneum. The diagnosis of mesenteric cystic lymphangioma is the most often mentioned during the first years of life with a clinical picture polymorphic ranging from simple abdominal pain to a symptomatic occlusion with peritonitis, while there are few cases diagnosed in prenatal described in the literature. On the occasion of an illustrative clinical observation, we report the case of a giant intraperitoneal cystic lymphangioma diagnosed in antenatal by an obstetric ultrasound performed on a 2nd parent 33 weeks of amenorrhea. We discuss the antenatal signs which should raise suspicion of diagnosis and lead to magnetic resonance imaging (MRI), as well as the care to be adopted pre- and postnatally.
