Fibromuscular dysplasia : what the radiologist should know‎ : a pictorial review

Abstract : Fibromuscular dysplasia (FMD) is an idiopathic, segmentary, non inflammatory and non atherosclerotic disease that can affect all layers of both small- and medium-caliber arteries. The prevalence of FMD is estimated between 4 and 6% in the renal arteries and between 0.3 and 3% in the cervicoencephalic arteries. FMD most frequently affects the renal, carotid, and vertebral arteries but it can theoretically affect any artery. Radiologists play an important role in the diagnosis of FMD and a good knowledge on FMD's conditions will certainly help reduce the delay between the first symptoms and the diagnosis. If the common string-of-beads aspect is well known, less common presentations have to be known. These less common imaging findings include: vascular loops, fusiform vascular ectasia, arterial dissection, aneurysm and subarachnoid hemorrhage. These radiologic presentations should be known from radiologists, in order to diagnose possible FMD, particularly when present in young females, or when associated with personal or familial hypertension, to reduce the delay between the onset of the first symptom and the final diagnosis. Thus, the patients have to be referred in specialized FMD centers for dedicated management.
