Catheter-based angiography of a renal artery in fibromuscular dysplasia
Typical appearance of multifocal fibromuscular dysplasia (multifocal FMD). Note the "string of beads" in the mid-distal right renal artery and its branches. The beading represents areas of constriction (by the fibrous webs) and dilatation.
