Question:

Characteristic imaging findings of fibromuscular dysplasia include:
1. Focal stenosis.
2. Double or triple renal artery.
3. "String of beads" sign.
4. Multiple stenoses and aneurysms.
5. Location at the origin of the renal artery.





Answer:

The correct answers for the question "Characteristic imaging findings of fibromuscular dysplasia include:" are:

1. Focal stenosis.

3. "String of beads" sign.

4. Multiple stenoses and aneurysms.



Explanation
[Characteristic imaging findings include focal stenosis or a "string of beads" appearance indicating multiple stenoses and aneurysms]. A double or triple renal artery is not a characteristic finding of FMD, but of course may be found in symptomatic or asymptomatic patients. FMD most often affects the middle and distal portion of the main renal artery or its segment branches in contrast to atherosclerotic disease, which tends to be located at the origin or proximal portion of the renal artery.

Abstract
We report on a patient with terminal renal insufficiency undergoing hemodialysis since four months. Imaging studies showed complete renal artery occlusion of a single kidney with collateral perfusion. Interventional recanalization of the renal artery was successful with a drop of serum creatinine from 1138 to 163 mol/l sparing the patient from further hemodialysis.
