Pediatric echocardiogram of partial anomalous left pulmonary artery (PALPA) in a 4-month-old patient. (A) Grayscale and (B) color Doppler images demonstrate a second left pulmonary artery (LPA) (the PALPA) arising from the right pulmonary artery (RPA). Color aliasing is noted at the stenotic lower RPA. AO = aorta, MPA = main pulmonary artery.

(A, B) Contrast-enhanced CT angiographic chest three-dimensional volume-rendered images obtained using cinematic rendering in the (A) anterosuperior and (B) posterosuperior views. The main pulmonary artery trunk (black arrow) bifurcation gives rise to the left upper lobe pulmonary artery (white arrow) and right pulmonary artery (RPA) (black arrowhead). The stenotic lower RPA is again demonstrated (curved white arrow). The partial anomalous left pulmonary artery (PALPA) (white arrowhead) is seen arising from the RPA. (C) Three-dimensional volume-rendered image of the pulmonary arteries with superimposed airways demonstrates the PALPA coursing posterior to the left mainstem bronchus (LB). RB = right mainstem bronchus, T = trachea.
