title: Dextroconvexity of the mediastinum in the azygoesophageal recess: a normal CT variant in young adults.
abstract: Dextroconvexity of mediastinal contents in the azygo-esophageal recess can occur as a normal variant in young adults with relatively small anteroposterior thoracic dimensions. In older patients with a relatively larger thoracic size, the configuration of the azygo-esophageal recess is more concave. Patient age and thorax size should be considered when interpreting possible azygo-esophageal recess pathology.
