Partial anomalous pulmonary venous return (PAPVR) consists of a wide spectrum of uncommon congenital anomalies in which one or more pulmonary veins drain directly or indirectly into the right atrium as a result of abnormalities during pulmonary venous embryogenesis. Thus, keen understanding of the underlying embryological origins of the pulmonary venous system is essential to recognize the variations in PAPVR, and radiological assessment is imperative to elucidate the complex anomalous cardiovascular anatomy for subsequent clinical and surgical management. The purpose of this educational exhibit is to provide a brief discussion of the embryological development of pulmonary veins and a detailed review of the diverse array of PAPVR variations with the aid of various case studies and CT imaging findings including sinus venosus atrial septal defect, Scimitar syndrome and anomalous left pulmonary veins.
