The diagnosis of left ventricular aneurysm on routine chest examination can be elusive. Six cases are presented which illustrate a radiographic sign not previously emphasized: a soft tissue border seen retrosternally or superiorly on lateral chest film produced by the wall of the aneurysm silhouetting against the midline cardiac shadow. This sign is not always present since it is dependent on the direction of projection of the aneurysm. However, when observed, it should suggest the proper diagnosis.
在常规胸部检查中，左心室动脉瘤的诊断可能难以捉摸。本文介绍了6例病例，这些病例说明了一种以前未被强调的放射学征象：在侧位胸片上，动脉瘤壁与心脏中线阴影形成对比，在胸骨后或上方可见软组织边界。由于该征象取决于动脉瘤的投影方向，因此并不总是存在。然而，一旦观察到，就应提示正确的诊断。
