Angiographic pattern change in fibromuscular dysplasia. A case report.
Fibromuscular dysplasia (FMD) is an angiopathy that commonly affects the renal arteries but may affect other medium to large arteries, including the carotid artery. It has a variety of angiography appearances, the most common of which is a string-of-beads pattern consisting of a segment of alternating stenoses and dilatations. This case documents that these patterns are not necessarily fixed. An initial angiogram in a patient with neurologic symptoms shows a string-of-beads pattern in the carotid artery. Later, this pattern is seen to convert to a smooth tubular form on follow-up arteriography. FMD may present angiographically as a dynamic process.
