An anomalous origin of the right pulmonary artery is a rare phenomenon in neonates with transposition of the great arteries. We report a case of dextro-transposition of the great arteries with an anomalous right pulmonary artery originating from the innominate artery, diagnosed by cardiac CT angiography and the cinematic rendering technique. Although surgical correction was possible, it was deferred due to complex anatomy and parental preference. This case highlights the diagnostic value and role of advanced imaging in complex congenital heart disease.
