Secondary hypertension is more common in children than adults, and renal disease is the most common cause. Several studies have shown a relationship between abnormalities in renal arterial vascularity and the onset of hypertension. We reported a case of hypertension in a 10-year-old girl with elevated plasma renin and normal aldosterone levels. Antihypertensive therapy was necessary to achieve blood pressure control, and the final diagnosis of hypertension was obtained from Computed Tomography (CT) angiography demonstrating unusual renal vascular abnormalities.
