ANSWER
Answer	Intestinal duplication cyst
Comments	Duplication cysts are rare congenital anomalies of the alimentary tract. The majority of duplication cysts are symptomatic within the first 2 years of life. Ultrasound of the abdomen shows a classical layered cyst wall with alternating hyperechoic and hypoechoic layers. This is known as the gut signature sign and is pathognomonic for alimentary tract duplication.
