Abstract
Ultrasonographic evaluation of a suspected abdominal mass in children is becoming routine. Recognition of a rare congenital anomaly known as duplication of the gastrointestinal tract might aid in diagnosis and obviate the need for an extensive workup. Two cases are presented that clearly demonstrate the ultrasonographic spectrum of findings in this condition, ranging from a sonolucent cyst to an echogenic mass. An echogenic inner rim seen ultrasonographically is highly suggestive of the diagnosis.
