Cystic lymphangioma of the jejunal mesentery in an adult.

Mesenteric lymphangioma is a rare entity with only case reports and small series available in the published literature. We report a 48 years female patient with non-specific abdominal complaints and a cystic mass identified at CT and US. At laparotomy we found a 5 cm cystic mass developed between the folds of the mesentery of the jejunum and an adhesion between the transverse mesocolon and the ileum. Surgery consisted in sectioning of the adhesion and complete removal of the mass, which proved to be a cystic lymphangioma. The symptoms disappeared after surgery with no signs of recurrence at 5 years follow-up.
