This presentation originates from a study of 55 patients with Scimitar Syndrome over a 21 year period at our institution. The aim of this exhibit is to:  Define Scimitar syndrome and review the embryology.  Using CT imaging demonstrate the morphological heterogeneity of Scimitar Syndrome including systemic collaterals, pulmonary venous and bronchial anomalies. Demonstrate unusual variants including left sided Scimitar syndrome, horseshoe lung and the spectrum of assiocicated congenital anomalies including aortic atresia, coarctation and anomalous coronary origin.  

Anatomy and Embryology of Scimitar Syndrome CT and catheter angiographic findings in classical Scimitar Syndrome including; Pulmonary venous return Systemic arterial pulmonary collaterals Tracheobronchial anomalies Parenchymal lung Atypical Scimitar Syndrome  Anomalous coronary origin Co-arctation Hypoplastic left ventricle SVC anomalies

The major teaching points of this exhibit are; Scimitar syndrome is a rare condition with classical and unusual associations.   CT enables the radiologist to diagnose not only the vascular anomalies but parenchymal, bronchial and synchronous cardiac abnormalities. The benefits of a non-invasive and relatively low radiation dose imaging.
