title: Peristalsis in duplication cyst: a new diagnostic sonographic finding.
abstract: Ultrasonography is useful in the evaluation of enteric duplication cysts in infants. Typically, there is an anechoic fluid-filled lumen with a double-layered surrounding wall. This case report documents an additional sonographic finding which has not been recorded: peristaltic contractions of the cyst wall. This provides a real-time observation which is specific in the pre-operative diagnosis of neonatal cystic abdominal masses.
