Dissecting aortic aneurysm in childhood and adolescence. Case report and literature review.

A 15-year-old adolescent male with dissecting aortic aneurysm is presented. His young age, lack of predisposing factors, and fulminant course with rapid progression to death precluded a correct antemortem diagnosis. Review of the literature reveals that most instances of dissecting aortic aneurysm in childhood and adolescence are associated with predisposing conditions, especially congenital cardiovascular anomalies. The clinical picture is generally characteristic. Prompt evaluation and therapy may be lifesaving.
