Fibromuscular dysplasia of the cervico-cephalic arteries.

Six cases of fibromuscular dysplasia of the cervical and cephalic portions of the internal carotid arteries, including their intracranial branches are reported. It should perhaps be pointed out that one of the cases was from the Sudan. As far as we know, the condition has never before been reported in a male African. The condition was associated with an intracranial aneurysm in four of our cases. To our knowledge only three autopsied cases of fibromuscular dysplasia involving intracranial arteries are on record. In our six cases the diagnosis was based on angiographic evidence, and three of the cases, two with intracranial involvement, were verified post mortem.
