Scimitar syndrome on imaging. (A) Posteroanterior chest radiograph with green arrow labelling the curvilinear opacity corresponding to the anomalous pulmonary vein, or ‘scimitar sign’. (B) Computed tomography three-dimensional reconstruction with pulmonary veins coloured in red and pulmonary arteries coloured in blue. A large anomalous right pulmonary vein, the scimitar vein (labelled ‘SV’), is seen emptying into the inferior vena cava (labelled ‘IVC’).
