Fibromuscular dysplasia. A case report with multivessel vascular involvement.

A case of multivessel fibromuscular dysplasia involving the cervico-cephalic arteries, the right renal artery and the iliac arteries is reported. It was associated with reversible bilateral internal carotid arteries and vertebral arteries dissection, left thalamic infarct, right hemorrhagic cerebellar infarct, renovascular hypertension and intermittent claudication of the right lower limb. This report indicates that fibromuscular dysplasia is a systemic angiopathy. Renovascular hypertension may foster the appearance of complication such as dissection of the arteries affected by fibromuscular dysplasia. In the case investigated the dissection of cervico-cephalic arteries was followed by spontaneous healing and a favourable neurological outcome whereas at the iliac arteries a rapid deterioration was observed.
