Left pulmonary artery (LPA) sling is a very rare anomaly in which the LPA arises distally, far from the right pulmonary artery on the right side of the distal trachea, turns sharply leftwards around the trachea and courses to the left lung hilum through the space between the trachea and esophagus. LPA sling is often associated with distal tracheal narrowing, due to either intrinsic stenosis or secondary compression by the anomaly itself. To our knowledge, prenatal diagnosis of LPA sling has not been reported so far. We report a case in which LPA sling was diagnosed during fetal ultrasound examination.
