    Abstract

    Intestinal duplication cysts are characterized by the attachment to some part of the gastrointestinal tract with which a blood supply is shared, and have an epithelial lining resembling some part of the alimentary tract. A 15-month-old female was admitted to our hospital with cyclic irritability, vomiting, and blood-tinged stool. The results of an ultrasound showed an ileocolic intussusception and a 1.3 cm cystic mass had double-wall sign and a Y-configuration with an adjacent ileal loop. She had a past history of two ileocolic intussusceptions. The cystic mass was considered to be a pathologic lead point, so resection and end-to-end anastomosis was performed. The gross and histologic evaluation of the specimen demonstrated a 2.4×2.4 cm cystic mass containing yellow mucoid fluid and the cyst wall was lined with intestinal and gastric mucosa and enclosed by a layer of muscle, which was shared with the adjacent ileum.

    (A) Ultrasound shows a cystic mass with a double-layered wall consisting of an echogenic inner layer (black arrow) and a hypoechoic outer layer (white arrow). (B) A Y-configuration is shown at the junction of the cyst and adjacent small bowel (oval line).

    Fig. 2
    On a contrast-enhanced CT scan, a 2.4 cm cystic-like mass with an enhancing wall (arrow) is demonstrated in the left lower peritoneal cavity adjacent to an ileal loop.

    Fig. 3
    The gross specimen demonstrates a 2.4×2.4 cm cystic mass adjacent to an ileal loop.

    Fig. 4
    (A) Low-power histologic photomicrograph demonstrates the cyst with a layer of muscle (arrowhead) is shared with adjacent ileum, and the white box represents a low magnification lesion of (B) (H&E, ×12.5). (B) The cystic outer wall is lined with shared normal intestinal mucosa (yellow arrow) and the inner wall is lined with ectopic gastric mucosa (black arrow; H&E, ×40).

    Fig. 5
    The cystic wall consists of inner hyperechoic and outer hypoechoic layers, known as the double-wall sign, and two Y-configurations (white line) are visible at the junctions of the cyst and adjacent small bowel loop (ref. 14).
