Imaging features of gastrointestinal tract duplications in infants and children: from oesophagus to rectum.

Abstract

Gastrointestinal tract duplications are uncommon congenital abnormalities arising anywhere along the alimentary tract. The most common modalities used to image duplications are US and contrast medium examinations. CT and MRI are less often used, but can be helpful in difficult cases that require a multiplanar approach. In this article, we discuss and illustrate a wide spectrum of gastrointestinal tract duplications from the oesophagus to the rectum, and illustrate the associated abnormalities of gastrointestinal tract duplications.
