Cystic Conundrum: Unraveling a Rare Pediatric Mesenteric Lymphangioma

A BSTRACT Lymphangioma is a rare malformation of the lymphatic system, primarily congenital but occasionally acquired. Nearly 95% of lymphangiomas occur in the head, neck, and axial regions, whereas the remaining 5% are found in the mesenteries, abdominal viscera, lungs, retroperitoneum, and mediastinum. Mesenteric cystic lymphangioma (MCL) is a benign lymphatic system malformation. It is an extremely rare tumor, with an incidence of approximately 1 in 250,000 cases. Due to its rarity and the variability in its clinical and radiological presentation, MCL poses diagnostic challenges that can lead to adverse outcomes. Here, we report an interesting case of MCL in a 3-year-old child.
