Esophageal bronchus

Last revised by Dr Mohamed Saber on 27 Oct 2020

Esophageal bronchus, a.k.a. communicating bronchopulmonary foregut malformation, refers to the rare occurrence where a bronchus arises directly from the esophagus.

It is more common in females with a M:F of 1:2 2

Esophageal bronchi may be the main bronchus, which gives rise to esophageal lung, or may be a lobar bronchus, most commonly a lower lobe bronchus.

Arterial supply and venous drainage are variable:

  • arterial supply: may arise directly from the thoracic aorta
  • venous drainage: may be to systemic or pulmonary circulations
  • barium fills the bronchus and first-order branches 2
