MRI of the brain without contrast demonstrated features consistent with PRES (Figure 1). MRI of the abdomen with contrast showed a small right kidney and a high-grade proximal renal artery stenosis (Figures 1 and 2A).
Angiography of right renal artery (A), pre-balloon dilation and stenting (B), balloon dilation (C) stenting (D), post-balloon dilation and stenting.

MRI of the abdomen with contrast showed a small right kidney and a high-grade proximal renal artery stenosis (Figures 1 and 2A). The right renal artery was balloon dilated to 50% as shown in Figure 2B. Following repeat balloon angioplasty, the patient's renal artery progressively re-occluded over 15 min requiring a 4 x 14 Genesis stent to maintain adequate flow, as shown in Figures 2C,D.
