Pulmonary artery sling

Case contributed by Dr Hani Salam

Case Discussion

A neonate with pulmonary sling.

CTA clearly demonstrates the aberrant left pulmonary artery arising from the right pulmonary artery passing between the trachea and esophagus.

Coronal reformat demonstrates the main bronchi have a very horizontal course (low T-shaped carina) highly suggestive of tracheal stenosis due to complete cartilage rings—that is, a rigid “O”-ring trachea without a pars membranacea. This is usually associated with high fatality.
