Fibromuscular Dysplasia

Fibromuscular dysplasia (FMD) is the abnormal development or growth of cells in the walls of arteries which cause the vessels to narrow. Arteries within the brain and kidneys can be affected. A characteristic "string of beads" pattern caused by the alternating narrowing and enlarging of the artery can be seen on angiogram.
