Isolated intracranial fibromuscular dysplasia is rare and may present with cerebrovascular events. It should be considered as etiology of stroke in otherwise healthy young patients. Though diagnosis is often challenging, characteristic morphologies may be revealed on magnetic resonance and catheter angiography. Cephalocervical fibromuscular dysplasia typically involves the extracranial portion of the internal carotid artery (nearly 95%). This rare case demonstrates isolated intracranial fibromuscular dysplasia in a 19-year-old female with left caudate and genu of internal capsule stroke.
