HighlightsIntraabdominal lymphatic malformations present most commonly in the small bowel mesentery (60%), mesocolon (24%), and retroperitoneum (14.5%).Cystic lymphatic malformations are classified as macrocystic, microcystic, or mixed cystic.Complications can include abscess, intestinal obstruction, volvulus, bleeding, and/or rupture.Secondary abscess formation may result in incomplete characterization of the pathologic process at the time of frozen section interpretation.Resection of bowel may be necessary in cases where the mesentery is involved.
