Volvulus on a Giant Cystic Lymphangioma: Two Cases of the Rare Cause of Intestinal Obstruction in Children

Abstract

Cystic lymphangiomas (CLs) are rare benign vascular malformations, primarily occurring in children, often in the cervicofacial region. Intra-abdominal lymphangiomas, though less common, can lead to serious complications such as volvulus and intestinal obstruction. We report two cases of volvulus resulting from mesenteric CLs (MCLs) in pediatric patients. Both patients presented with acute intestinal obstruction and underwent emergency laparotomy, which included complete resection of the cysts, resulting in favorable postoperative outcomes. These cases underscore the necessity of considering CLs in the differential diagnosis of pediatric abdominal masses and the importance of prompt surgical intervention to prevent severe complications. Additionally, we discuss the pathophysiology, imaging techniques, surgical management, and histopathological findings associated with this rare condition.
