Multidetector Computed Tomography in the Diagnosis of Pulmonary Sling: Case Report

Hong Kong J Radiol 2004;7:215-8

Pulmonary artery sling is a rare developmental vascular abnormality. In this abnormality, the left pulmonary artery arises from the right pulmonary artery, courses between the trachea and oesophagus, and forms a sling around the distal trachea. This arrangement gives rise to upper respiratory obstruction. This case report, of a 3- month-old boy, highlights the use of multidetector computed tomography as an imaging modality to diagnose pulmonary artery sling and to enable rapid diagnosis of airway obstruction in infants.
