The anomalous origin of the right pulmonary artery from the ascending aorta in a neonate was diagnosed by two-dimensional and colour directed Doppler echocardiography. An anomalous arterial vessel coursing towards the right lung originated from the posterolateral aspect of the ascending aorta. It could be visualized in parasternal and suprasternal views. The normal bifurcation of the pulmonary trunk was absent. Colour Doppler examination aided in clearer delineation and consequent correct identification of the anomalous vessel as the right pulmonary artery.
