CTICasesAnomalous Bronchial Artery Origin from the Left Subclavian Artery
Imaging findings
CT shows a bronchial artery with an anomalous origin from the left subclavian artery, coursing between the trachea and esophagus before branching into the left hilum.
Key takeaways
This was regarded as an incidental normal-anatomy variant rather than a disease process; an anomalous bronchial artery origin from the subclavian artery is an underrecognized variant that the presenters had not previously encountered, useful to recognize so it is not mistaken for a pathologic vessel.
