Abstract

Left pulmonary artery sling (LPAS) is a rare congenital anomaly in which the left pulmonary artery originates from the
posterior aspect of the right pulmonary artery and courses between the trachea and esophagus to reach the left lung. This anomaly causes distal tracheal and/or right main-stem bronchus compression. Most LPAS cases are associated with early symptom onset, around 2 month-old, and have severe respiratory distress within the first year of life. There are two major types of LPAS based on the location of LPA and abnormal bronchial branching. The diagnosis can be made by using various imaging modalities. Herein, we present the imaging characteristics on multi detectors computed tomography of 5 LPAS cases with respiratory distress (2 months to 12 months).
