Abstract
Alimentary tract duplication cysts are rare congenital anomalies that can occur anywhere along the gastrointestinal tract. Ileocecal duplication cysts, a subset of enteric duplication cysts (EDCs), are particularly uncommon and often present with nonspecific symptoms, making preoperative diagnosis difficult. We report a case of a 7-year-old female who presented with intermittent abdominal pain and vomiting for 1 month. Physical examination revealed right iliac fossa tenderness and mild abdominal distension, with imaging suggesting a mesenteric cyst. Laparoscopic exploration identified a mass attached to the ileocecal region, necessitating right hemicolectomy. Histopathology confirmed an ileocecal duplication cyst. Most EDCs are diagnosed within the first two years of life, making this a rare late presentation. This case underscores the importance of considering EDCs in older children with vague abdominal symptoms. Although imaging aids evaluation, surgical exploration remains essential for definitive diagnosis and treatment. Laparoscopic resection effectively prevents complications such as obstruction or perforation.
