The patient was a 12-month-old boy in whom an intraabdominal cystic lesion was detected on fetal ultrasound examination performed at 21 weeks of gestation. Postnatal abdominal ultrasound revealed a hypoechoic image of about 20 mm size with a septal wall near the lower liver and the right kidney, which was monitored with suspicion of a mesenteric cyst. At 7 months of age, abdominal ultrasound and abdominal MRI showed that the cyst had increased in size, and the patient was introduced to our department. Laparoscopic observation at the umbilical incision with the suspected mesenteric cyst was carried out at 18 months of age. An ileocecal ileal duplication of about 4 cm size was detected, and an attempt was made to nucleate it, but a single-incisional laparoscopic-assisted ileocecal resection was performed in order to cause a stenosis. The mass did not block the intestine and lumen, and the fluid was mucous. A histopathological examination showed a cystic lesion and a muscle layer partially continuous from the proper muscle layer of the ileum, and the lumen is covered with MUC5AC(+) and MUC2(–) columnar epithelia. It was accompanied by a MUC6(+) pyloric-gland-like intrinsic gastric gland. Postoperatively, the patient progressed without signs of stenosis and was discharged on the 4th postoperative day.
