In the classic scimitar syndrome, a pulmonary vein draining all or part of the right lung enters the inferior vena cava. A variant is described with the same roentgenographic appearance, but with drainage of the anomalous pulmonary vein into both the inferior vena cava and the left atrium; the atrial septum was intact. This case, together with six others reported elsewhere, reminds us that the scimitar sign has both false positives and false negatives. Therefore, the diagnosis of scimitar syndrome cannot be made with certainty from a plain x-ray film.
在典型的弯刀综合征中，引流右肺全部或部分的肺静脉汇入下腔静脉。有一种变异型，其具有相同的X线表现，但异常肺静脉同时引流至下腔静脉和左心房；房间隔完整。该病例以及其他地方报道的另外6例病例提醒我们，弯刀征既有假阳性也有假阴性。因此，仅通过普通X线片不能确诊弯刀综合征。
