• The azygoesophageal line is an
    • anatomical landmark representing
      the
      • interface between the azygos vein and the esophagus,
    • typically located at the T5 to T6 vertebral levels.
    • It serves as a
      • critical
        reference point when assessing the posterior mediastinum and
      • identifying surrounding structures.
    • The azygos vein, which runs
      along the right side of the thoracic spine
      • drains blood from the thoracic wall and upper lumbar regions into the superior vena cava, while
    • the esophagus lies
      • anterior to the aorta and posterior to the
        trachea.
    • Abnormalities in the azygo-esophageal line can indicate
      pathological conditions such as
      • mediastinal masses (tumors or
        lymphadenopathy),
      • esophageal varices,
      • strictures, or anomalies of the azygos vein.

Azygo-esophageal line Note the right border of the line is formed by the ascending azygous vein (red arrowheads) and the azygous vein appears as a rounded density above the right main stem bronchus (blue arrowhead) just before it enters the upstream SVC. Air in the noted in the  esophagus (pink arrowheads).
