“Uneven-sized eyes” sign on echocardiography in a young girl with pulmonary artery sling and tracheal bronchus

Received 3 January 2016; revision accepted for publication 18 January 2016. A 15-year-old girl was referred for evaluation of occasional chest pain and syncope for years. Chest radiography showed a tracheal bronchus (figure 1A, arrow). The left pulmonary artery arose from the right pulmonary artery and passing posteriorly to the echoes arising from the air-filled trachea in the parasternal short-axis view of the transthoracic echocardiography (figure 1B). There were two different sized vessels, the “uneven-sized eyes” sign, beneath the aortic arch in the suprasternal long-axis view. The larger vessel was the right pulmonary artery and the smaller vessel with high velocity systolic jet near the aortic arch was the aberrant left pulmonary artery (figure 1c, arrow). The diagnosis of pulmonary artery sling with tracheal bronchus was confirmed by MDCT and 3D reconstruction (figure 1C). Since our patient was asymptomatic and pneumonia had not recurred recently, we decided to adopt a wait-and-see approach.
