What is a common notable physical finding in a patient with fibromuscular dysplasia?

In patients with fibromuscular dysplasia, a common notable physical finding is a renal artery bruit. Fibromuscular dysplasia typically affects the renal arteries, leading to stenosis or narrowing of these blood vessels. This can cause turbulent blood flow, which produces a characteristic sound that can be heard upon auscultation, known as a bruit.

The presence of a renal artery bruit is significant because it often indicates renal artery involvement and can help in the diagnosis of conditions related to renal hypertension, a common complication of fibromuscular dysplasia. This bruit can often be detected in patients who have significant renal artery stenosis due to the condition.

In the context of the other choices, diminished femoral pulses may suggest peripheral vascular disease, but is not specifically associated with fibromuscular dysplasia. Hearing loss is not a typical finding related to this condition. Webbed fingers are associated with congenital syndromes but are not linked to fibromuscular dysplasia. Therefore, the identification of a renal artery bruit serves as a crucial clue for clinicians suspecting fibromuscular dysplasia.
