FMD can be found in almost every artery in the human body, but most often affects the carotid, vertebral, renal arteries and even those that supply the intestines, arms, and the legs.[1] Patients may present with FMD in multiple vessels. FMD has been pathologically categorized into three types of classifications: Multi-focal, focal, and adventitial; referring to the particular layer of arterial wall being affected.[2]
