Fibromuscular Dysplasia : Symptoms

What are the symptoms of Fibromuscular Dysplasia?

Some people with FMD do not have any symptoms or findings on physical examination. The signs and/or symptoms that a person may experience depend on the arteries affected and the degree of narrowing or enlargement within them. Any pain or clinical sign related to FMD typically comes from the organ that is supplied by the artery. For example, FMD in the kidney arteries may cause high blood pressure. Progression of disease can also result in shrinkage of the kidney (ischemic renal atrophy), due to lack of oxygen.

Patients with FMD in the carotid arteries may have many different symptoms including dizziness, temporary blurring or loss of vision, ringing, swooshing, or buzzing in the ears, vertigo (feeling as if the room was spinning around you), neck pain, and/or headaches. However, a person with severe FMD may have neurological symptoms involving the facial muscles (drooping of the face, for example), which can be due to a stroke or mini-stroke (transient ischemic attack, TIA) or tear in a carotid artery (carotid dissection).

People with carotid FMD have a higher risk for aneurysms inside of the brain; therefore, every patient with FMD of the carotid arteries should undergo a Magnetic Resonance Angiogram (MRA) or a Computed Tomography Angiogram (CTA) at some time. If left untreated, an aneurysm of the brain can rupture and cause bleeding in the brain (intracranial hemorrhage), which is a type of stroke.

FMD involving the mesenteric arteries (arteries that supply the intestines, liver and spleen with blood) can result in abdominal pain after eating and unintended weight loss. FMD in the arms and legs can cause limb muscle discomfort with use (claudication).
