Abstract
Evaluation of the mediastinum in moderate to severe achalasia demonstrates how it accommodates a significantly dilated esophagus. Dilatation and movement of the esophagus toward paths of least resistance are determined by the location and orientation of normal mediastinal structures. Changes in presentation of lines, stripes, and interfaces in achalasia and why they occur provide insight into how the mediastinum responds to esophageal dilatation in other diseases (for example, esophageal carcinoma). Evaluation of the changes in the mediastinum with esophageal dilatation enhances understanding of normal anatomy and its transition to an abnormal state.
