[Systemic fibromuscular dysplasia. Supra aortic and renal artery involvement]

We report a 39 years old male presenting with an intense hemicrania pain in the tract of the carotid artery and Claude Bernard Horner syndrome. The patient had also a high blood pressure. Magnetic resonance imaging demonstrated a left carotid artery fibrodysplastic disease. Conventional angiography of 4 cerebral vessels showed a dissection of the left carotid artery and fibromuscular dysplasia of the left vertebral artery. Renal angiography showed a stenosis and occlusion of renal artery with radiological exclusion of right kidney. On the left side there was a stenosis and occlusion of segmental branches. The diagnostic importance of Claude Bernard Horner syndrome and the need to study renal artery involvement when carotid dissection is accompanied with high blood pressure, is highlighted.
