Abstract Cecal duplication cysts (CDCs) are rare congenital anomalies, accounting for only 0.4% of gastrointestinal duplications. They may mimic common abdominal pathologies such as intussusception, making preoperative diagnosis difficult. A 7-year-old male presented with upper abdominal pain for 3 days. Imaging suggested a possible ileocolic intussusception with a mesenteric cyst. An attempt at noninvasive reduction was unsuccessful, necessitating laparotomy. Intraoperatively, a 5 cm × 4 cm duplication cyst was identified at the distal cecum. Resection of the cyst with the terminal ileum and cecum, followed by ileo-ascending anastomosis, was performed. The cyst shared a wall with the cecum and contained mucoid material. Histopathology confirmed a duplication cyst with colonic-type epithelium. The postoperative course was uneventful, and the patient was discharged in stable condition. This case emphasizes the need to consider duplication cysts in the differential diagnosis of pediatric intussusception. CDCs are rare and may present as intussusception. Awareness and early surgical management are essential to prevent complications. Complete resection with anastomosis remains the treatment of choice.
