45. Patient presenting with transient phosphenes and headache: A case of fibromuscular dysplasia

Fibromuscular dysplasia (FMD), is a nonatherosclerotic, noninflammatory vascular disease commonly affecting the renal, extracranial carotid and vertebral arteries (VA). Etiology remains unknown. Clinical presentation is determined by distribution of arteries affected. Carotid artery involvement is associated with headache, TIA, stroke, pulsatile tinnitus, or may be asymptomatic. Treatment is being recommended in symptomatic cases. A 49-year-old Caucasian woman, was presented to our emergency department for transient phosphenes in right eye, followed by front-temporal headache. Cranial CT was normal, cervical duplex ultrasound and transcranial Doppler were suggestive of a tandem stenosis of the distal tract of left carotid internal artery (ICA) and middle cerebral artery. MR-angiography documented a fibrodisplasic aspect of the middle and distal ICA, hypoplasia of the right VA, an hypoplasic A1 segment of the left anterior cerebral artery and a small aneurysm (
