Pulmonary artery sling anomaly presenting with unilateral lung hyperinflation: A case report

Özet

Left pulmonary artery sling is a rare congenital pulmonary artery anomaly whichpresents with tracheal compression due to vascular ring formation. Rarely,patients may present with hyperinflation or collapse of a lung unilaterally.We present a one-month-old infant with dyspnea who had a hyperinflatedleft lung and collapsed right lung. Computed tomography (CT) angiographydemonstrated pulmonary sling causing compression of proximal parts of rightand left main bronchi. This case highlights the importance of three-dimensionalCT angiography in evaluation of thoracic vascular anomalies associated withtracheobronchial pathologies.
