A 12-year-old boy presented with hypertension and intermittent lower extremity claudication. Breath-hold high spatial resolution MRA at 3.0 T (gradient recalled echo sequence; 10 ml of Magnevist) revealed abdominal aortic coarctation (Fig. 1, thin long arrow), severely narrowed right renal artery and atrophy of the ipsilateral kidney (Fig. 1b, arrowhead), and hypertrophied inferior mesenteric artery (Fig. 1a, thick short arrow) feeding the superior mesenteric artery (Fig. 1a, thin short arrow) through the arc of Riolan (Fig. 1a, arrowhead). The child had previously undergone placement of an aorto-aortic graft (Fig. 1, thick long arrow).
