Fibromuscular Dysplasia of Common Carotid Artery A Case Report

Abstract

A case of presumed fibromuscular dysplasia involving the left common carotid artery with formation of fusiform aneurysm of the whole length of the common carotid artery, and a distal web-like lesion, is described in a 25 year old female patient. The angiographic appearance of the lesion is uncommon, as is the involvement of the common carotid artery. The literature is reviewed.

Cerebrovascular complications of fibromuscular dysplasia

“…1). Histologically, this appearance is analogous to medial arterial wall fibroplasias, with this "string of beads" being due to multiple dilatations along the course of the artery separated by irregularly spaced concentric tight stenoses [17,19,84]. A second angiographic appearance of FMD is a smooth, tubular stenosis (unifocal or multifocal) involving long sections of the ICA.…”

“…Conventional catheter angiography is considered the gold standard for diagnosing cervicocephalic FMD [83]. A variety of abnormal patterns may be seen angiographically [17,19,20,83,84]. The most common FMD appearance observed is the classically recognized angiographic appearance of "string of beads" (Fig.…”
