A teenager with longstanding arterial hypertension was admitted for acute pneumonia treatment. New onset atypical chest pain for the last months and aortic valve regurgitation were also present. A dissecting aneurysm of the ascending aorta with moderate aortic valve regurgitation was evidenced by laboratorial diagnostic. Aneurismectomy with aortic valve preservation and coronary artery reimplantation was carried out.
