Lymphangiomas are a rare benign proliferation of the lymphatic system. Intra-abdominal lymphangioma is rare and accounts for <5% of lymphangioma cases. Cystic mesenteric lymphangioma is extremely rare and accounts for <1% of abdominal lymphangiomas. Abdominal swelling, pain, vomiting, and constipation are common clinical presentations. We report a case of a 5-year-old boy with no significant medical history of illness who presented with acute abdomen. Preoperative accurate diagnosis by radiological modalities is very difficult. Surgical excision is the choice of treatment. Definitive diagnosis requires histopathological examination. [ABSTRACT FROM AUTHOR]
