Fibromuscular dysplasia in an adult male as a cause of renal artery stenosis and secondary hypertension treated with renal artery stenting.

Background: Renovascular hypertension due to fibromuscular dysplasia is an uncommon cause of secondary hypertension and is more common in females. This entity is an important treatable cause of secondary hypertension.

Case presentation: We report the case of a 21-year-old asymptomatic male found to have high blood pressure on routine checkup. Renal angiogram revealed fibromuscular dysplasia involving the right renal artery. He underwent percutaneous angioplasty with complete recovery. The single antihypertensive which he was on was stopped next month.

Conclusion: Fibromuscular dysplasia causing stenosis of renal artery is uncommon. High degree of suspicion is required for the timely diagnosis and treatment of this potentially treatable cause of secondary hypertension.
