[[Pediatric cerebrovascular disease]].
----


The most common presentation of cerebrovascular disease is an [[ischemic stroke]] or mini-stroke and sometimes a [[hemorrhagic stroke]]. [[Hypertension]] (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in [[atherosclerosis]].

Cerebrovascular diseases have traditionally been classified, diagnosed and managed based on their luminal characteristics. However, over the past several years, several advancements in MRI techniques have ushered in [[high-resolution vessel wall imaging]] (HR-VWI), enabling evaluation of intracranial vessel wall pathology. These advancements now allow us to differentiate diseases which have a common angiographic appearance but vastly different natural histories (i.e. moyamoya versus atherosclerosis, reversible cerebral vasoconstriction syndrome versus vasculitis, stable versus unstable intracranial aneurysms)
