Caecal duplication cysts (DCs) are rare anomalies and presentation varies according to size, site, the mucosal lining of the cyst, and age of the patient. The rarity of the condition and varied clinical presentation makes it difficult to diagnose preoperatively. A high index of suspicion and intraoperative examination of the whole bowel is essential to localize intraluminal DC. We herein describe a case of an intraluminal caecal DC in an infant along with its presentation, management, and review of pertinent literature.
