"Pile of plates" appearance on angiography suggests diagnosis of
assistant
The correct answer is  Angiography: "string of beads"/"Pile of plates" appearance of FMD is classically seen on angiography. Fibromuscular dysplasia most commonly causes small stenoses along a vessel with intervening areas of dilatation (small aneurysms), creating a "string of beads" appearance. Less commonly the stenosis has a smooth tapered appearance. Fibromuscular dysplasia also weakens the vessel wall which predisposes to dissection ref Robbins 9/e pg 678
