CTICasesScimitar Syndrome
Imaging findings
3D CT reconstruction demonstrates a large anomalous pulmonary vein (Scimitar vein) draining the entire right lung into the inferior vena cava (IVC) just above the right atrium. The right lung is mildly hypoplastic.
Key takeaways
Scimitar syndrome (partial anomalous pulmonary venous return) is characterized by anomalous venous drainage of the right lung to the IVC. The anatomy is highly variable, often associated with right lung hypoplasia and systemic arterial supply.
