Fig. 3D —33-year-old man with suspected renovascular hypertension.
Coronal subvolume maximum intensity projections from navigator-gated
steady-state free precession (Nav SSFP) MR angiography (A) and
contrast-enhanced MR angiography (CE-MRA) (B) with digital subtraction
angiography correlation show injection of both aorta (C) and accessory
(D) renal arteries. Nav SSFP and CE-MRA agreed that both main arteries
were nondiseased. Arrows represent the accessory artery, which was seen and
thought to be diseased on both Nav SSFP and CE-MRA. Accessory artery was
believed to represent intimal fibroplasia (an atypical form of fibromuscular
dysplasia) and to be responsible for patient's hypertension.
