Ultrasound image of a single symptomatic carotid stenosis disclosed as fibromuscular dysplasia

Abstract

Fibromuscular dysplasia (FMD) is an uncommon idiopathic noninflammatory nonatherosclerotic angiopathy that occurs in young to middle-aged individuals and more frequently in women. It consists of abnormalities of smooth muscle and fibrous and elastic tissue, affecting small- to medium-sized vessels. It has been demonstrated in almost every vascular bed, but renal arteries are most commonly involved (60 to 75%), followed by the cervicocranial arteries (25 to 30%).1 FMD leads to arterial narrowing, and clinical manifestations include hypertension and stroke.2 Although FMD is a pathology diagnosis, most often it is made by conventional angiography. There are only few reports of FMD with color duplex flow imaging (CDFI) because the typical high cervical lesion location is difficult to access for ultrasound.3,4⇓, We present here the case of a woman who experienced an acute stroke due to a stenosis of the proximal internal carotid artery (ICA). A 43-year-old healthy woman …
