Enteric duplication cysts and reversed intestinal rotation (RIR) are rare congenital anomalies, with their coexistence being exceptionally uncommon. We report a 4-year-old girl who presented with chronic anemia and intermittent abdominal symptoms since infancy. Detailed workup for medical causes of anemia was inconclusive. Computed tomography of the abdomen revealed intestinal malrotation with a grossly dilated small bowel loop. Intraoperative findings revealed a long duodenojejunal tubular duplication with a separate mesentery (Type 1a) and RIR. The patient underwent a Ladd's procedure, resection of the duplication cyst, and end-to-end anastomosis. This case underscores the anatomical rarity, varied clinical presentation, and challenges in making an accurate and timely diagnosis in such a case.
