Esophageal bronchus
Esophageal bronchus refers to the rare occurrence where a bronchus arises directly from the esophagus.
On this page:
Epidemiology
It is more common in females with a M:F of 1:2 2.
Gross anatomy
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.
Associations
Blood supply
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
Radiographic appearance
Plain radiograph
- unilateral alveolar opacity and air bronchogram as a result of aspiration 4
- mediastinal shift to the affected side 2
Fluoroscopy
- barium fills the bronchus and first-order branches 2
