A Case of Intestinal Duplication Cyst Identified as Pathological Lead Point in a Child with Recurrent Intussusception / 대한소아소화기영양학회지

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 2.4x2.4 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.
