• 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.
