A 21-year-old female patient complaining of hemiparesis was diagnosed with right middle cerebral artery infarction. No risk factor was found, despite an extensive young-age stroke work-up, except her history of marijuana use. The patient had smoked marijuana for treating depression for more than five years. Magnetic resonance angiography showed multifocal intra- and extracranial stenoses, suggesting cannabinoid-induced vasculopathy. Since the use of illicit drugs has increased nationwide, physicians should consider it as a possible cause of a stroke due to an unknown etiology.

Fibromuscular dysplasiais an uncommon condition of idiopathic, non-inflammatory and non-atherosclerotic disease of the musculature of arterial walls. The disease is rare, but it commonly affects young and middle aged women. Isolated intracranial cerebral fibromuscular dysplasia is extremely rare because cerebral fibromuscular dysplasia usually affects extracranial vessels. A 20-year-old woman was admitted with light hemiplegia and global aphasia. Brain MRI and MRA demonstrated acute left middle cerebral artery territory infarction with a multifocal stenosis and dilatation of the left middle cerebra artery and left internal carotid. The characteristic conventional cerebral angiographic findings demonstrated a typical string-of-beads appearance in the left distal internal carotid artery and proxiaml portion of the left middle cerebral artery, which suggested a medial type fibromuscular dysplasia. We report a case of isolated intracranial fibromuscular dysplasia with left middle cerebral artery territory infarction. Fibromuscular dysplasia should he considered as a stroke risk factors in children and young adults, especially in patients with no known cardiovascular risk factors.
