- Deviation of the azygosesophageal recess line
Deviation of the azygo-oesophageal recess can be normal or pathological.
The azygo-oesophageal recess is formed by the interface between the right lung and the mediastinal reflection of the azygos vein and oesophagus. The line has a variable appearance 1:
in its upper third, it deviates to the right, where it may either be straight or concave relative to the right lung; in children and young adults, it can be convex relative to the right lung
in its middle third, it is usually straight, but may be slightly convex relative to the right lung near the right pulmonary veins
in its lower third, it is usually straight
The azygo-oesophageal recess may be deviated by conditions that affect the middle or posterior mediastinal compartments including 2:
subcarinal lymphadenopathy
oesophageal disease
