<bold>Fig CA 18-1 Essential (idiopathic) hypertension.</bold> (A) Frontal and (B) lateral views of the chest demonstrate characteristic tortuosity of the aorta (arrows), especially the ascending portion. Because the elevated blood pressure has caused left ventricular hypertrophy without dilatation, the radiographic appearance of the cardiac silhouette remains normal.
