The pediatric esophagus is most frequently evaluated dynamically with real-time fluoroscopy using orally administered contrast material. However, direct anatomic information is limited to the esophageal mucosa. Intramural abnormalities may or may not be visible on fluoroscopic examination, and extraluminal abnormalities can only be inferred. The purpose of this pictorial essay is to familiarize the reader with the CT appearances of esophageal lesions in children. Although not traditionally used to evaluate the esophagus in pediatric patients, CT can be a valuable tool for evaluating intrinsic abnormalities of the esophagus and pathologic processes that directly affect the esophagus and adjacent mediastinum.
