Accidente cerebrovascular pediátrico secundario a displasia fibromuscular

We present the case of a 13 year-old patient diagnosed with fibromuscular dysplasia (FMD) by angiographic study, with “string of beads” image of internal carotid, after undergoing two ischemic strokes in nine days. Conservative treatment with acetylsalicylic acid at antiaggregant doses was decided. Twenty months later the clinical progress is favorable without presenting any new episodes. FMD is a very uncommon cause of stroke in childhood. Little is known about its etiology. In spite of it usually being an asymptomatic disease, it must be considered in cases of repeated or inexplicable strokes. Its prognosis and treatment is controversial, due to the limited number of pediatric patients with this pathology.
