Fibromuscular dysplasia of the basilar artery. Report of a case.

ABSTRACT

A case of fibromuscular dysplasia (FMD), mostly involving the basilar artery, associated with an intracranial aneurysm, is presented. Although the patient was symptomatic, the typical angiographic pattern is felt to be in this case an incidental finding. However the potential for FMD to produce severe neurological impairment is emphasized. The case is used as a basis for discussing shortly the incidence, the characteristic radiological appearance, the relationship with the presence of intracranial aneurysms and the therapeutic problems of FMD.
