Reveal Findings

CT – Axial, multiplanar MIP and 3D volume rendered images show origin of the right pulmonary artery from the aorta; the left pulmonary artery arises from the pulmonary trunk; note the juxtaductal narrowing of the aorta.

Reveal Discussion

Origin of the right pulmonary artery from the aorta is a rare anomaly resulting in a left to right shunt, heart failure and if untreated death in early infancy. The lesion may result from two different developmental defects: abnormal septation of the primitive truncus or atresia of the proximal portion of the sixth right aortic arch and persistence of the distal portion as a right ductus arteriosus.
