Congenital cerebrovascular anomalies in the pediatric age group are myriad with diverse etiologies. The purpose of this paper is to provide an imaging overview of congenital vascular malformations and vascular tumors, as these conditions are varied and the characteristic vascular abnormality may even suggest the underlying systemic condition in helping to guide further management. For example, the identification of an arterial anomaly such as agenesis/hypoplasia/duplication may warrant further evaluation for an associated syndrome. ⋯ An accurate description of vascular lesions is critical for understanding the natural history of the disease process and ultimately for guiding treatment. An important example of this includes Sturge-Weber syndrome, which is often incorrectly viewed as an arteriovenous malformation, but actually a type of venous malformation. Another example which is important to recognize includes the differentiation between an infantile hemangioma and a vascular malformation, particularly as the course of the pathology and the treatment is so different between the two.
