[Monogenic and acquired cerebral vasculopathies as a cause of cerebrovascular disease in pediatrics].

Cerebral vasculopathies represent the most frequent risk factor for pediatric stroke. Although uncommon, monogenic vasculopathies show significant genotype- phenotype variability and involve vessels of different calibers. Among acquired forms, focal cerebral arteriopathy is the most frequent entity. Neuroimaging plays a central role in diagnosis and follow-up of vasculopathies. Recognition of specific patterns of vascular involvement helps guide diagnosis, assess recurrence risk, and inform therapeutic decisions.
