A large right sided pulmonary vein is seen supradiaphragmatic inferior vena cava (IVC) in a patient with Scimitar Syndrome. b Axial CT image of same patient as in (a). The white arrow indicates the anomalous right pulmonary vein. The asymmetry of the pulmonary vasculature provides a clue to identifying the abnormality. The right hemidiaphragm is elevated consistent with hypoplasia of the right lower lobe, a common association with anomalous pulmonary venous drainage. c Chest radiograph of a paediatric patient, demonstrating a tubular opacity in the right paracardiac region consistent with a scimitar vein (arrow). d Coronal MIP CT image showing a large right pulmonary vein draining into the infradiaphragmatic IVC
