Scimitar Sign: Causes & Reasons

Possible Causes for Scimitar Sign

The 'scimitar sign' on plain chest radiograph is most commonly attributed to the presence of a scimitar vein, which is a variant of partial anomalous pulmonary venous drainage [ncbi.nlm.nih.gov]

The anomalous vein is seen as a curved, tubular structure noted lateral to the right heart border, coursing inferiorly (Scimitar sign) (Fig. 9 ). [jcongenitalcardiology.biomedcentral.com]

The scimitar vein is frequently initially discovered on chest X-ray by the curvilinear “scimitar sword” appearance of the anomalous venous flow to the IVC. [annals.in]

Congenital Unilateral Pulmonary Hypoplasia

The radiographic appearance of the pulmonary vein descending along the right cardiac border is characteristic (scimitar sign) (, 1,, 45 ) (, ,, ,, Fig 11b ). [pubs.rsna.org]

This vessel increases in caliber in the caudal direction(“scimitar sign,” so called because of its resemblance to a Turkish sword). [slideshare.net]

There is loss of the right heart shadow due to the right pulmonary hypoplasia and to the pulmonary vein coursing to the right cardiophrenic angle (scimitar sign) (arrows). [pubs.rsna.org]
