AbstractThe early diagnosis and complete anatomic evaluation of pulmonary artery sling, a congenital vascular anomaly in which left pulmonary artery arises from the right pulmonary artery, is paramount for proper patient management, because patients with this disorder frequently have other congenital anomalies resulting in high morbidity and mortality. Until recently, pulmonary artery sling in the neonate has been established with standard radiologic imaging studies such as plain radiographs, barium swallow studies, fluoroscopy-guided airway studies, and echocardiograms. However, with the development and widespread availability of multidetector computed tomography, pulmonary artery sling is increasingly evaluated with this newer technology. This case report presents a rare incidence of type 2 hypoplastic pulmonary artery sling in a neonate associated with right lung agenesis, hypoplastic aortic arch, and long segment tracheal stenosis. Multidetector computed tomography combined with 3-dimensional evaluation was particularly helpful in making a correct diagnosis of the complicated anatomic anomalies found in this case.
