1. Findings
Scimitar Sign on CT
66 year old female presents with dyspnea
Coronal CT shows a curvilinear sword shaped structure in the right lower lung field that represents the right lower pulmonary vein (red arrowhead, b) that is draining anomalously into the inferior vena cava(blue arrowhead b).
The pulmonary arteries are enlarged reflecting pulmonary hypertension secondary to longstanding left to right shunt
Findings are consistent with partial anomalous pulmonary venous return and the sword like shape of the vein has been assigned the name scimitar syndrome The PAPVR is often associated with hypoplasia of the lung on the affected side.
