title: Radiographic visualization of left ventricular aneurysms on lateral chest film.
abstract: 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.
