Dissecting aortic aneurysm in systemic lupus erythematosus.

Many cardiovascular manifestations have been described in systemic lupus erythematosus (SLE). Aortic involvement, however, is very rare. We describe a 30-year-old woman with SLE who presented with extensive aortic dissection, and review the few reported cases. We discuss possible pathogenic mechanisms for aortic involvement in lupus and the appropriate diagnostic work-up.
