Vascular Lesions of the Mediastinum

This article highlights the vascular lesions that present as mediastinal masses. Some radiographic findings represent interesting clinical findings that do not require further intervention, such as a persistent left superior vena cava. Differentiating these findings from true pathologic entities then becomes paramount. In other cases, the clinical presentation will prompt immediate surgical or medical management to mitigate or prevent the mortality and morbidity associated with the condition, such as acute aortic dissection. Although specific details about the management of each clinical or pathologic entity are beyond the scope of this article, a brief mention is made of currently recommended therapy where appropriate.
