Vascular malformations of the brain are a heterogeneous group of disorders involving the blood vessels of the brain. These entities are relatively rare; therefore, most primary care physicians are somewhat unfamiliar with their clinical implications and management. Vascular malformations of the brain range from the completely benign capillary telangiectasia to the potentially fatal arterio-venous malformation. This article reviews the distinct natural histories, etiologies and treatments of four major types of malformations: capillary telangiectasia, developmental venous anomaly, cavernous malformation and arteriovenous malformation.
